+# Dictionaries are lists of words to accept unconditionally
+
+While check spelling will complain about a whitelisted word
+which is no longer present, you can include things here even if
+they are not otherwise present in the repository.
+
+E.g., you could include a list of system APIs here, or potential
+contributors (so that if a future commit includes their name,
+it'll be accepted).

+### Notes for Future Maintainers
+
+This was originally imported by @miniksa in March 2020.
+
+The provenance information (where it came from and which commit) is stored in the file `cgmanifest.json` in the same directory as this readme.
+Please update the provenance information in that file when ingesting an updated version of the dependent library.
+That provenance file is automatically read and inventoried by Microsoft systems to ensure compliance with appropiate governance standards.
+
+## What should be done to update this in the future?
+
+1. Go to pinam45/dynamic_bitset repository on GitHub.
+2. Take the entire contents of the include directory wholesale and drop it in the root directory here.
+3. Don't change anything about it.
+4. Validate that the license in the root of the repository didn't change and update it if so. It is sitting in the same directory as this readme. 
+   If it changed dramatically, ensure that it is still compatible with our license scheme. Also update the NOTICE file in the root of our repository to declare the third-party usage.
+5. Submit the pull.

+### Notes for Future Maintainers
+
+This was originally imported by @miniksa in March 2020.
+
+The provenance information (where it came from and which commit) is stored in the file `cgmanifest.json` in the same directory as this readme.
+Please update the provenance information in that file when ingesting an updated version of the dependent library.
+That provenance file is automatically read and inventoried by Microsoft systems to ensure compliance with appropiate governance standards.
+
+## What should be done to update this in the future?
+
+1. Go to kimwalisch/libpopcnt repository on GitHub.
+2. Take the `libpopcnt.h` file.
+3. Don't change anything about it.
+4. Validate that the `LICENSE` in the root of the repository didn't change and update it if so. It is sitting in the same directory as this readme. 
+   If it changed dramatically, ensure that it is still compatible with our license scheme. Also update the NOTICE file in the root of our repository to declare the third-party usage.
+5. Submit the pull.

+# Formatted Copy
+
+## Abstract
+
+When copying text, the Terminal should provide the option of including formatting. Not all apps that receive text allow for picking which format you want when pasting. The default should be to only copy plain text, based on the response from this poll on Twitter.
+
+![Twitter poll](twitter-poll.png)
+
+## Solution Proposals
+
+A proposal for the right click behavior as well as two user settings proposals are described below. The conclusion the team arrived at is at the bottom under the [Conclusions section](#conclusions).
+
+1. [Settings option 1 - global setting](#settings-option-1---global-setting)
+2. [Settings option 2 - key binding argument](#settings-option-2---key-binding-argument)
+3. [Right click behavior](#right-click-behavior)
+
+### Settings option 1 - global setting
+
+We could have a global setting that when enabled, would copy formatting to the clipboard on all copy operations.
+
+### Settings option 2 - key binding argument
+
+We could add an argument to the `copy` key binding argument to allow for formatted copying when the user chooses to do so.
+
+### Right click behavior
+
+By default, right clicking to copy would only copy the plain text.
+
+## UI/UX Design
+
+### Settings option 1 - global setting
+
+a. The user could list which kinds of formats they want included when they copy. When right clicking, they would copy with these formats.
+
+`"copyFormats": ["html","rtf","plain"]`
+
+b. We could also just combine html and rtf into a single boolean. Users would either get plain text only (`false`) or all formatting (`true`) onto their clipboard. If this is set to `true`, the default right click behavior is reversed: right clicking copies the formatting.
+
+`"copyFormatting": true`
+
+### Settings option 2 - key binding argument
+
+a. Just like the `trimWhitespace` argument you can add to the `copy` key binding, we could add one for text formatting. This would not change the right click behavior.
+
+`{"command": {"action": "copy", "keepFormatting": true}, "keys": "ctrl+a"}`
+
+b. We could also split out the html and rtf formats. The right click behavior would still stay as default.
+
+`{"command": {"action": "copy", "formats": ["html","rtf","plain"]}, "keys": "ctrl+a"}`
+
+## Capabilities
+
+### Accessibility
+
+This shouldn't affect accessibility.
+
+### Security
+
+This does not affect security.
+
+### Reliability
+
+This does not affect reliability.
+
+### Compatibility
+
+This breaks the existing behavior of always copying the formatting. The justification for breaking this default behavior is in response to the community saying the default should be plain text only.
+
+### Performance, Power, and Efficiency
+
+## Potential Issues
+
+One possible issue is that discovering how to copy the formatting might be difficult to find. We could mitigate this by adding it into the settings.json file and commenting it out.
+
+## Conclusions
+
+The team has decided to have plain text as the default copy behavior and to enable formatted copying with a global setting that accepts a boolean value (settings option 1 - global setting, option b). In the future, we can modify this setting to also accept an array, so the user can specify which formats they would like to copy. Additionally, a key binding can be added to allow for greater flexibility.
+
+## Future considerations
+
+We could always add an additional option if people want more flexibility. For example, if we ship a global setting now, we could ship a key binding later that lets you choose how you want to copy, and vice versa. Additionally, we can add functionality to the global setting that allows for specific formats or styles to be copied.

+_This is a draft spec. It should be considered a work-in-progress._
+
+# Command Palette
+
+## Abstract
+
+This spec covers the addition of a "command palette" to the Windows Terminal.
+The Command Palette is a GUI that the user can activate to search for and
+execute commands. Beneficially, the command palette allows the user to execute
+commands _even if they aren't bound to a keybinding_.
+
+## Inspiration
+
+This feature is largely inspired by the "Command Palette" in text editors like
+VsCode, Sublime Text and others.
+
+This spec was initially drafted in [a
+comment](https://github.com/microsoft/terminal/issues/2046#issuecomment-514219791)
+in [#2046]. That was authored during the annual Microsoft Hackathon, where I
+proceeded to prototype the solution. This spec is influenced by things I learned
+prototyping.
+
+## Solution Design
+
+First off, for the sake of clarity, we'll rename the `command` of a keybinding
+to `action`. This will help keep the mental model between commands and actions
+clearer. When deserializing keybindings, we'll include a check for the old
+`command` key to migrate it.
+
+We'll introduce a new top-level array to the user settings, under the key
+`commands`. `commands` will contain an array of commands, each with the
+following schema:
+
+```js
+{
+    "name": string,
+    "action": string,
+    "icon": string
+    "args": object?,
+}
+```
+
+Command names should be human-friendly names of actions, though they don't need
+to necessarily be related to the action that it fires. For example, a command
+with `newTab` as the action could have `"Open New Tab"` as the name.
+
+The command will be parsed into a new class, `Command`:
+
+```c++
+class Command
+{
+    winrt::hstring Name();
+    winrt::TerminalApp::ActionAndArgs ActionAndArgs();
+    winrt::hstring IconSource();
+}
+```
+
+We'll add another structure in GlobalAppSettings to hold all these actions. It
+will just be a `std::vector<Command>` in `GlobalAppSettings`.
+
+We'll need app to be able to turn this vector into a `ListView`, or similar, so
+that we can display this list of actions. Each element in the view will be
+intrinsically associated with the `Command` object it's associated with. In
+order to support this, we'll make `Command` a winrt type that implements
+`Windows.UI.Xaml.Data.INotifyPropertyChanged`. This will let us bind the XAML
+element to the winrt type.
+
+When an element is clicked on in the list of commands, we'll raise the event
+corresponding to that `ShortcutAction`. `AppKeyBindings` already does a great
+job of dispatching `ShortcutActions` (and their associated arguments), so we'll
+re-use that. We'll pull the basic parts of dispatching `ActionAndArgs`
+callbacks into another class, `ShortcutActionDispatch`, with a single
+`PerformAction(ActionAndArgs)` method (and events for each action).
+`AppKeyBindings` will be initialized with a reference to the
+`ShortcutActionDispatch` object, so that it can call `PerformAction` on it.
+Additionally, by having a singular `ShortcutActionDispatch` instance, we won't
+need to re-hook up the ShortcutAction keybindings each time we re-load the
+settings.
+
+In `App`, when someone clicks on an item in the list, we'll get the
+`ActionAndArgs` associated with that list element, and call PerformAction on
+the app's `ShortcutActionDispatch`. This will trigger the event handler just the
+same as pressing the keybinding.
+
+### Commands for each profile?
+
+[#3879] Is a request for being able to launch a profile directly, via the
+command palette. Essentially, the user will type the name of a profile, and hit
+enter to launch that profile. I quite like this idea, but with the current spec,
+this won't work great. We'd need to manually have one entry in the command
+palette for each profile, and every time the user adds a profile, they'd need to
+update the list of commands to add a new entry for that profile as well.
+
+This is a fairly complicated addition to this feature, so I'd hold it for
+"Command Palette v2", though I believe it's solution deserves special
+consideration from the outset.
+
+I suggest that we need a mechanism by which the user can specify a single
+command that would be expanded to one command for every profile in the list of
+profiles. Consider the following sample:
+
+```json
+    "commands": [
+        {
+            "expandOn": "profiles",
+            "icon": "${profile.icon}",
+            "name": "New Tab with ${profile.name}",
+            "command": { "action": "newTab", "profile": "${profile.name}" }
+        },
+        {
+            "expandOn": "profiles",
+            "icon": "${profile.icon}",
+            "name": "New Vertical Split with ${profile.name}",
+            "command": { "action": "splitPane", "split":"vertical", "profile": "${profile.name}" }
+        }
+    ],
+```
+
+In this example:
+* The `"expandOn": "profiles"` property indicates that each command should be
+  repeated for each individual profile.
+* The `${profile.name}` value is treated as "when expanded, use the given
+  profile's name". This allows each command to use the `name` and `icon`
+  properties of a `Profile` to customize the text of the command.
+
+To ensure that this works correctly, we'll need to make sure to expand these
+commands after all the other settings have been parsed, presumably in the
+`Validate` phase. If we do it earlier, it's possible that not all the profiles
+from various sources will have been added yet, which would lead to an incomplete
+command list.
+
+We'll need to have a placeholder property to indicate that a command should be
+expanded for each `Profile`. When the command is first parsed, we'll leave the
+format strings `${...}` unexpanded at this time. Then, in the validate phase,
+when we encounter a `"expandOn": "profiles"` command, we'll remove it from the
+list, and use it as a prototype to generate commands for every `Profile` in our
+profiles list. We'll do a string find-and-replace on the format strings to
+replace them with the values from the profile, before adding the completed
+command to the list of commands.
+
+Of course, how does this work with localization? Considering the [section
+below](#localization), we'd update the built-in commands to the following:
+
+```json
+    "commands": [
+        {
+            "iterateOn": "profiles",
+            "icon": "${profile.icon}",
+            "name": { "key": "NewTabWithProfileCommandName" },
+            "command": { "action": "newTab", "profile": "${profile.name}" }
+        },
+        {
+            "iterateOn": "profiles",
+            "icon": "${profile.icon}",
+            "name": { "key": "NewVerticalSplitWithProfileCommandName" },
+            "command": { "action": "splitPane", "split":"vertical", "profile": "${profile.name}" }
+        }
+    ],
+```
+
+In this example, we'll look up the `NewTabWithProfileCommandName` resource when
+we're first parsing the command, to find a string similar to `"New Tab with
+${profile.name}"`. When we then later expand the command, we'll see the
+`${profile.name}` bit from the resource, and expand that like we normally would.
+
+Trickily, we'll need to make sure to have a helper for replacing strings like
+this that can be used for general purpose arg parsing. As you can see, the
+`profile` property of the `newTab` command also needs the name of the profile.
+Either the command validation will need to go through and update these strings
+manually, or we'll need another of enabling these `IActionArgs` classes to fill
+those parameters in based on the profile being used. Perhaps the command
+pre-expansion could just stash the json for the action, then expand it later?
+This implementation detail is why this particular feature is not slated for
+inclusion in an initial Command Palette implementation.
+
+## UI/UX Design
+
+We'll add another action that can be used to toggle the visibility of the
+command palette. Pressing that keybinding will bring up the command palette.
+
+When the command palette appears, we'll want it to appear as a single overlay
+over all of the panes of the Terminal. The drop-down will be centered
+horizontally, dropping down from the top (from the tab row). When commands are
+entered, it will be implied that they are delivered to the focused terminal
+pane. This will help avoid two problematic scenarios that could arise from
+having the command palette attache to a single pane:
+  * When attached to a single pane, it might be very easy for the UI to quickly
+    become cluttered, especially at smaller pane sizes.
+  * This avoids the "find the overlay problem" which is common in editors like
+    VS where the dialog appears attached to the active editor pane.
+
+The palette will consist of two main UI elements: a text box for searching for
+commands, and a list of commands.
+
+The list of commands will be populated with all the commands by default. Each
+command will appear like a `MenuFlyoutItem`, with an icon at the left (if it has
+one) and the name visible. When opened, the palette will automatically highlight
+the first entry in the list.
+
+The user can navigate the list of entries with the arrow keys. Hitting enter
+will close the palette and execute the action that's highlighted. Hitting escape
+will dismiss the palette, returning control to the terminal. When the palette is
+closed for any reason (executing a command, dismissing with either escape or the
+`toggleCommandPalette` keybinding), we'll clear out any search text from the
+palette, so the user can start fresh again.
+
+We'll also want to enable the command palette to be filterable, so that the user
+can type the name of a command, and the command palette will automatically
+filter the list of commands. This should be more powerful then just a simple
+string compare - the user should be able to type a search string, and get all
+the commands that match a "fuzzy search" for that string. This will allow users
+to find the command they're looking for without needing to type the entire
+command.
+
+For example, consider the following list of commands:
+
+```json
+    "commands": [
+        { "icon": null, "name": "New Tab", "action": "newTab" },
+        { "icon": null, "name": "Close Tab", "action": "closeTab" },
+        { "icon": null, "name": "Close Pane", "action": "closePane" },
+        { "icon": null, "name": "[-] Split Horizontal", "action": "splitHorizontal" },
+        { "icon": null, "name": "[ | ] Split Vertical", "action": "splitVertical" },
+        { "icon": null, "name": "Next Tab", "action": "nextTab" },
+        { "icon": null, "name": "Prev Tab", "action": "prevTab" },
+        { "icon": null, "name": "Open Settings", "action": "openSettings" },
+        { "icon": null, "name": "Open Media Controls", "action": "openTestPane" }
+    ],
+```
+
+* "open" should return both "**Open** Settings" and "**Open** Media Controls".
+* "Tab" would return "New **Tab**", "Close **Tab**", "Next **Tab**" and "Prev
+  **Tab**".
+* "P" would return "Close **P**ane", "[-] S**p**lit Horizontal", "[ | ]
+  S**p**lit Vertical", "**P**rev Tab", "O**p**en Settings" and "O**p**en Media
+  Controls".
+* Even more powerfully, "sv" would return "[ | ] Split Vertical" (by matching
+  the **S** in "Split", then the **V** in "Vertical"). This is a great example
+  of how a user could execute a command with very few keystrokes.
+
+As the user types, we should **bold** each matching character in the command
+name, to show how their input correlates to the results on screen.
+
+## Capabilities
+
+### Accessibility
+
+As the entire command palette will be a native XAML element, it'll automatically
+be hooked up to the UIA tree, allowing for screen readers to naturally find it.
+ * When the palette is opened, it will automatically receive focus.
+ * The terminal panes will not be able to be interacted with while the palette
+   is open, which will help keep the UIA tree simple while the palette is open.
+
+### Security
+
+This should not introduce any _new_ security concerns. We're relying on the
+security of jsoncpp for parsing json. Adding new keys to the settings file
+will rely on jsoncpp's ability to securely parse those json values.
+
+### Reliability
+
+We'll need to make sure that invalid commands are ignored. A command could be
+invalid because:
+* it has a null `name`, or a name with the empty string for a value.
+* it has a null `action`, or an action specified that's not an actual
+  `ShortcutAction`.
+
+We'll ignore invalid commands from the user's settings, instead of hard
+crashing. I don't believe this is a scenario that warrants an error dialog to
+indicate to the user that there's a problem with the json.
+
+### Compatibility
+
+We will need to define default _commands_ for all the existing keybinding
+commands. With #754, we could add all the actions (that make sense) as commands
+to the commands list, so that everyone wouldn't need to define them manually.
+
+### Performance, Power, and Efficiency
+
+We'll be adding a few extra XAML elements to our tree which will certainly
+increase our runtime memory footprint while the palette is open.
+
+We'll additionally be introducing a few extra json values to parse, so that could
+increase our load times (though this will likely be negligible).
+
+## Potential Issues
+
+This will first require the work in [#1205] to work properly. Right now we
+heavily lean on the "focused" element to determine which terminal is "active".
+However, when the command palette is opened, focus will move out of the terminal
+control into the command palette, which leads to some hard to debug crashes.
+
+Additionally, we'll need to ensure that the "fuzzy search" algorithm proposed
+above will work for non-english languages, where a single character might be
+multiple `char`s long. As we'll be using a standard XAML text box for input, we
+won't need to worry about handling the input ourselves.
+
+### Localization
+
+Because we'll be shipping a set of default commands with the terminal, we should
+make sure that list of commands can be localizable. Each of the names we'll give
+to the commands should be locale-specific.
+
+To facilitate this, we'll use a special type of object in JSON that will let us
+specify a resource name in JSON. We'll use a syntax like the following to
+suggest that we should load a string from our resources, as opposed to using the
+value from the file:
+
+```json
+    "commands": [
+        { "icon": null, "name": { "key": "NewTabCommandName" }, "action": "newTab" },
+        { "icon": null, "name": { "key": "CloseTabCommandKey" }, "action": "closeTab" },
+        { "icon": null, "name": { "key": "ClosePaneCommandKey" }, "action": "closePane" },
+        { "icon": null, "name": { "key": "SplitHorizontalCommandKey" }, "action": "splitHorizontal" },
+        { "icon": null, "name": { "key": "SplitVerticalCommandKey" }, "action": "splitVertical" },
+        { "icon": null, "name": { "key": "NextTabCommandKey" }, "action": "nextTab" },
+        { "icon": null, "name": { "key": "PrevTabCommandKey" }, "action": "prevTab" },
+        { "icon": null, "name": { "key": "OpenSettingsCommandKey" }, "action": "openSettings" },
+    ],
+```
+
+We'll check at parse time if the `name` property is a string or an object. If
+it's a string, we'll treat that string as the literal text. Otherwise, if it's
+an object, we'll attempt to use the `key` property of that object to look up a
+string from our `ResourceDictionary`. This way, we'll be able to ship localized
+strings for all the built-in commands, while also allowing the user to easily
+add their own commands.
+
+During the spec review process, we considered other options for localization as
+well. The original proposal included options such as having one `defaults.json`
+file per-locale, and building the Terminal independently for each locale. Those
+were not really feasible options, so we instead settled on this solution, as it
+allowed us to leverage the existing localization support provided to us by the
+platform.
+
+The `{ "key": "resourceName" }` solution proposed here was also touched on in
+[#5280].
+
+
+## Future considerations
+
+* Commands will provide an easy point for allowing an extension to add its
+  actions to the UI, without forcing the user to bind the extension's actions to
+  a keybinding
+* Also discussed in [#2046] was the potential for adding a command that inputs a
+  certain commandline to be run by the shell. I felt that was out of scope for
+  this spec, so I'm not including it in detail. I believe that would be
+  accomplished by adding a `inputCommand` action, with two args: `commandline`,
+  a string, and `suppressNewline`, an optional bool, defaulted to false. The
+  `inputCommand` action would deliver the given `commandline` as input to the
+  connection, followed by a newline (as to execute the command).
+  `suppressNewline` would prevent the newline from being added. This would work
+  relatively well, so long as you're sitting at a shell prompt. If you were in
+  an application like `vim`, this might be handy for executing a sequence of
+  vim-specific keybindings. Otherwise, you're just going to end up writing a
+  commandline to the buffer of vim. It would be weird, but not unexpected.
+* Additionally mentioned in [#2046] was the potential for profile-scoped
+  commands. While that's a great idea, I believe it's out of scope for this
+  spec.
+* Once [#754] lands, we'll need to make sure to include commands for each action
+  manually in the default settings. This will add some overhead that the
+  developer will need to do whenever they add an action. That's unfortunate, but
+  will be largely beneficial to the end user.
+* We could theoretically also display the keybinding for a certain command in
+  the `ListViewItem` for the command. We'd need some way to correlate a
+  command's action to a keybinding's action. This could be done in a follow-up
+  task.
+* We might want to alter the fuzzy-search algorithm, to give higher precedence
+  in the results list to commands with more consecutive matching characters.
+  Alternatively we could give more weight to commands where the search matched
+  the initial character of words in the command.
+  - For example: `ot` would give more weight to "**O**pen **T**ab" than
+    "**O**pen Se**t**tings").
+* Another idea for a future spec is the concept of "nested commands", where a
+  single command has many sub-commands. This would hide the children commands
+  from the entire list of commands, allowing for much more succinct top-level
+  list of commands, and allowing related commands to be grouped together.
+  - For example, I have a text editor plugin that enables rendering markdown to
+    a number of different styles. To use that command in my text editor, first I
+    hit enter on the "Render Markdown..." command, then I select which style I
+    want to render to, in another list of options. This way, I don't need to
+    have three options for "Render Markdown to github", "Render Markdown to
+    gitlab", all in the top-level list.
+  - We probably also want to allow a nested command set to be evaluated at
+    runtime somehow. Like if we had a "Open New Tab..." command that then had a
+    nested menu with the list of profiles.
+* We may want to add a button to the New Tab Button's dropdown to "Show Command
+  Palette". I'm hesitant to keep adding new buttons to that UI, but the command
+  palette is otherwise not highly discoverable.
+  - We could add another button to the UI to toggle the visibility of the
+    command palette. This was the idea initially proposed in [#2046].
+  - For both these options, we may want a global setting to hide that button, to
+    keep the UI as minimal as possible.
+* [#1571] is a request for customizing the "new tab dropdown" menu. When we get
+  to discussing that design, we should consider also enabling users to add
+  commands from their list of commands to that menu as well.

+# Add Profiles To Jumplist
+
+## Abstract
+
+This spec outlines adding support for launching a profile from the jumplist. The main two points that will be detailed are:
+1. Adding jumplist support
+2. Adding the ability to open a profile from the jumplist
+
+The profiles available in the jumplist will match the profiles available in the application from the + dropdown. The scope of the jumplist feature is limited to desktop devices.
+
+## Inspiration
+The inspiration is to be able to quickly open the terminal with one of the configured profiles.
+
+## Terminology
+- Jumplist: This is the menu that appears when the application is right-clicked on the taskbar or the start menu.
+
+## Solution Design
+
+### Overview
+The jumplist has to be created/modified during the life-cycle of the application. The following is an outline of the steps to be performed (more details below)
+1. Load settings / profiles
+2. Create the jumplist with the initial profiles
+3. Maintain sync between the jumplist and profiles throughout the life of the application
+
+### Jumplist integration
+UWP provides an API to access to the jumplist through the [Windows.UI.StartScreen.JumpList class](https://docs.microsoft.com/en-us/uwp/api/windows.ui.startscreen.jumplist), however from previous attempts [1], the api does not work for the project architecture.
+Instead, we'll use the COM interface [ICustomDestinationList](https://docs.microsoft.com/en-us/windows/desktop/api/shobjidl_core/nn-shobjidl_core-icustomdestinationlist) [2] directly to create the jumplist. Since we are using Win32 apis, the work should be done in the `WindowsTerminal` project.
+
+Using `ICustomDestinationList` is straightforward with a few additions discussed in this section [below](#Implementation-notes). Resources for using the jumplist can be found [here](https://msdn.microsoft.com/en-us/library/windows/desktop/gg281362.aspx) and [here](https://www.codeproject.com/Articles/36561/Windows-7-Goodies-in-C-Jump-Lists).
+
+The basic overview:
+1. Get an instance of the `ICustomDestinationList` COM object
+2. Call `ICustomDestinationList.BeginList`
+3. Create an `IObjectCollection` COM object
+4. Create `IShellLink` COM objects for each profile and add them to the `IObjectCollection`
+5. Add the `IObjectCollection` to the `ICustomDestinationList`
+6. Call `ICustomDestination.CommitList`
+
+Note that the jumplist is replaced each time, instead of being updated.
+
+#### Approach
+One approach is to wrap the COM interfaces in a jumplist class and use that to add and remove items.
+
+#### What if there are multiple instances of the terminal application?
+There maybe multiple instances trying to update the jumplist at the same time.
+
+### Adding profiles to the jumplist
+To add the profiles to the jumplist there are some prerequisites that are needed
+- Be able to access settings / profiles from the `WindowsTerminal` project.
+- Detect when profiles are modified
+  - Created: Add a new profile to the jumplist when a new profile is created by the user
+  - Deleted: Remove the profile from the jumplist when the profile is removed by the user
+  - Modified: We'll have to sync profile name changes / icon changes with the jump list
+
+There are also different "categories" that we could add the profiles to. A jumplist can have items in a system category such as `Recent` or `Frequent` or a custom category. Jumplist items can also be a task. The difference between adding an item to a category or the task list is that items in a category can be `pinned` and `removed` from the jumplist by the user. Here is a summary of the two from the documentation [2]:
+- `Destinations can be files, folders, websites, or other content-based items, but are not necessarily file-backed. Destinations can be thought of as things or nouns`
+- `Tasks are common actions performed in an application that apply to all users of that application regardless of an individual's usage patterns. Tasks can be thought of as actions or verbs`
+
+Following this, it would be more appropriate to add the profiles to the `Tasks` list as we are launching a profile. Essentially each item in the jumplist will be a shortcut that opens the terminal and provides command line arguments.
+
+#### Implementation notes
+When specifying the icon to use in the `IShellLink` object, it does not appear to be able to read `ms-appx://` URIs such as ones for the default profile icons and also only able to read `.ico` files. The way that the UWP api is able to do it is by adding additional `PropertyKey`s to the `IShellLink` object [3]. Using these tools [JumpList](https://github.com/EricZimmerman/JumpList) and [Lnk Explorer](https://github.com/EricZimmerman/LECmd), we can examine what is different with UWP jumplists. When we examine the `.lnk` items that the jumplist uses, we can see that additional properties are added to the property store.

+| {436F2667-14E2-4FEB-B30A-146C53B5B674}\100 | Link Arguments                               | {61c54bbd-c2c6-5271-96e7-009a87ff44bf}                             |

+
+If we look at the property key `9f4c2855-9f79-4b39-a8d0-e1d42de1d5f3\29`, it specifies the uri for the icon and supports the `ms-appx://` scheme. So for icon support we can add that property key when creating the `IShellLink`. Also note that with this approach, it needs the `file://` uri scheme in the path for custom icons.
+
+### Launching the terminal from the jumplist
+The jumplist will launch the terminal by calling the executable alias `wt.exe` with arguments to indicate the profile. The command line arguments to use are tracked in issue [#607](https://github.com/microsoft/terminal/issues/607)
+
+## UI/UX Design
+No UI changes are needed. The jumplist is provided by Windows.
+
+### Localization
+Depending on how the jump list items will be worded.
+
+### Profile order
+The order of the profiles in the jumplist should match the order within the application.
+
+## Capabilities
+
+### Accessibility
+Will be provided by what Windows supports for jump lists
+
+### Security
+Should not introduce any new security issues
+
+### Reliability
+Should not introduce any new reliability issues
+
+### Compatibility
+Will have to add the ability to get notified of changes to the profile settings.
+
+### Performance, Power, and Efficiency
+The jumplist will have to be saved each time a profile change occurs but the frequency would be expected to be low.
+
+## Potential Issues
+
+#### Should it open a new instance of the terminal or open in a new tab?
+
+#### What should happen if a non existant profile is launched
+The jumplist is only updated when the application is running so the profiles could be modified or deleted outside and the jumplist will not be updated. Handling will be done by whatever handles the command line parsing.
+
+## Future considerations
+Other things could potentially be added to the jumplist other than profiles.

+    //     TerminalPage so that we can get at its implementation is wacky, so
+    //     this helper will do it correctly for you, even if this doesn't make a
+    //     ton of sense on the surface. This is also why you need to pass both a
+    //     projection and a com_ptr to this method.
+    //   * It will use the provided settings object to initialize the TerminalPage
+    //   * It will add the TerminalPage to the test Application, so that we can
+    //     get actual layout events. Much of the Terminal assumes there's a
+    //     non-zero ActualSize to the Terminal window, and adding the Page to
+    //     the Application will make it behave as expected.
+    //   * It will wait for the TerminalPage to finish initialization before
+    //     returning control to the caller. It does this by creating an event and
+    //     only setting the event when the TerminalPage raises its Initialized
+    //     event, to signal that startup is complete. At this point, there will
+    //     be one tab with the default profile in the page.
+    //   * It will also ensure that the first tab is focused, since that happens
+    //     asynchronously in the application typically.
+    // Arguments:
+    // - page: a TerminalPage implementation ptr that will receive the new TerminalPage instance

+
+// Method Description:
+// - This is a helper to determine which direction an "Automatic" split should
+//   happen in for a given pane, but without using the ActualWidth() and
+//   ActualHeight() methods. This is used during the initialization of the
+//   Terminal, when we could be processing many "split-pane" commands _before_
+//   we've ever laid out the Terminal for the first time. When this happens, the
+//   Pane's don't have an actual size yet. However, we'd still like to figure
+//   out how to do an "auto" split when these Panes are all laid out.
+// - This method assumes that the Pane we're attempting to split is `target`,
+//   and this method should be called on the root of a tree of Panes.
+// - We'll walk down the tree attempting to find `target`. As we traverse the
+//   tree, we'll reduce the size passed to each subsequent recursive call. The
+//   size passed to this method represents how much space this Pane _will_ have
+//   to use.
+//   * If this pane is a leaf, and it's the pane we're looking for, use the
+//     available space to calculate which direction to split in.
+//   * If this pane is _any other leaf_, then just return nullopt, to indicate
+//     that the `target` Pane is not down this branch.
+//   * If this pane is a parent, calculate how much space our children will be
+//     able to use, and recurse into them.
+// Arguments:
+// - target: The Pane we're attempting to split.
+// - availableSpace: The theoretical space that's available for this pane to be able to split.
+// Return Value:
+// - nullopt if `target` is not this pane or a child of this pane, otherwise the
