## Detailed Description of the Pull Request / Additional comments
Rough changelog:
Normally saving is triggered to occur every 30s, or sooner if a window is created/closed. The existing behavior of saving on last close is maintained to bypass that throttling. The automatic saving allows for crash recovery. Additionally all window layouts will be saved upon taking the `quit` action.
For loading we will check if we are the first window, that there are any saved layouts, and if the setting is enabled, and then depending on if we were given command line args or startup actions.
- create a new window for each saved layout, or
- take the first layout for our self and then a new window for each other layout.
This also saves the layout when the quit action is taken.
Misc changes
- A -s,--saved argument was added to the command line to facilitate opening all of the windows with the right settings. This also means that while a terminal session is running you can do wt -s idx to open a copy of window idx. There isn't a stable ordering of which idx each window gets saved as (it is whatever the iteration order of _peasants is), so it is just a cute hack for now.
- All position calculation has been moved up to AppHost this does mean we need to awkwardly pass around positions in a couple of unexpected places, but no solution was perfect.
- Renamed "Open tabs from a previous session" to "Open windows from a previous session". (not reflected in video below)
- Now save runtime tab color and window names
- Only enabled for non-elevated windows
- Add some change tracking to ApplicationState

## Detailed Description of the Pull Request / Additional comments
While testing the save/quit features a number of issues were found that were caused by poor synchronization on the monarch, resulting in various unexpected crashes. Because this uses std collections, and I didn't see any builtin winrt multithreaded containers I went with the somewhat heavy-handed mutex approach.
e.g.
- https://github.com/microsoft/terminal/pull/11083#issuecomment-916218353
- https://github.com/microsoft/terminal/pull/11083#issuecomment-916220521
- https://github.com/microsoft/terminal/pull/11143/#discussion_r704738433
This also makes it so that on quit peasants don't try to become the monarch, and the monarch closes their peasant last to prevent elections from happening.
<!-- Describe how you validated the behavior. Add automated tests wherever possible, but list manual validation steps taken as well -->
## Validation Steps Performed
Create many windows (hold down ctrl-shift-n) then use the quit action from peasants/the monarch to make sure everything closes properly.
This PR simply replaces all uses of "TrayIcon" and "Tray" with "NotificationIcon" and "NotificationArea" to be more accurate. Originally I kinda wanted to only replace all occurrences of it in settings and user facing things, but I figured I might as well make it consistent throughout all of our code.
Fix infinite loop when trying to summon a window after close.
In #10972 code was added to try to clean up state manually when a window
was closed instead of waiting for it to be detected as a dead peasant.
Unfortunately I didn't know any better and missed cleaning up
`_mruPeasants` as well. The result is there would be an infinite loop
in `_getMostRecentPeasant` since `_getPeasant` will only clean up ids if
it finds a peasant, not if it doesn't find anything. This is the minimal
change to get this working, but it might be a good idea to make
`_getPeasant` be more thorough about cleanup.
## Validation Steps Performed
Tested that before the change we infinitely loop, and after the change
we summon correctly.
Closes#11215
Add the ability to quit all terminal instances. Doing this separately from the window layout saving ones to lessen the number of 1k+ line monsters I make y'all review.

## Detailed Description of the Pull Request / Additional comments
- Warn the user before they do so to give a chance to cancel
- Percolate a QuitAll event up to the monarch who then directs each peasant to clsoe.
- Leave a window-layout-saving-sized hole to add that feature on top
## Validation Steps Performed
- quit with one window (from the monarch)
- quit from the monarch with multiple windows
- quit from a peasant
- cancel the quit dialog
A brief summary of the behavior of the tray icon:
- There will only ever be one tray icon representing all windows.
- Left-Click on a Tray Icon brings up the MRU window.
- Right-Click on a Tray Icon brings up a Context Menu:
```
Focus Terminal
----------------
Windows --> Window ID 1 - <unnamed window>
Named Window
Named Window Again
```
- Focus Terminal will bring up the MRU window.
- Clicking on any of the Window "names" in the submenu will summon the window.
## Settings Changes
Two new global settings are introduced: `alwaysShowTrayIcon` and `minimizeToTray`. Here's a chart explaining the behavior with the two settings.
| | `alwaysShowTrayIcon:true` | `alwaysShowTrayIcon:false` |
|----------------------|------------------------------------------------------------------|------------------------------------------------------------------|
| `minimizeToTray:true` | tray icon is always shown. minimize button will hide the window. | tray icon is always shown. minimize button will hide the window. |
| `minimizeToTray:false` | tray icon is always shown. | tray icon is not shown ever. |
Closes#5727

## Summary of the Pull Request
This fixes a bug where if you had the `_quake` window open, and you tried to `globalSummon` it (not with the `quakeMode` action, but just with a plain-old `globalSummon` to activate the MRU window), we'd _create a new window_ instead of just summoning the `_quake` window.

## Detailed Description of the Pull Request / Additional comments
It's basically a one-line fix, I just had to update the function signature for `_getMostRecentPeasantID` to allow us to use it differently for glomming vs summoning. When glomming, `ignoreQuakeWindow` should be true. When summoning, `ignoreQuakeWindow` should be false.
This adds a `toggleVisibility` parameter to `globalSummon`.
* When `true` (default): when you press the global summon keybinding, and the window is currently the foreground window, we'll minimize the window.
* When `false`, we'll just do nothing.

## Detailed Description of the Pull Request / Additional comments
I've got nothing extra to add here. This one's pretty simple. I'm only targeting #9954 since that one laid so much foundation to build on, with the `SummonBehavior`
## Validation Steps Performed
Played with this for a while, and it's amazing.
This adds support for the `desktop` param to the `globalSummon` action. It accepts 3 values:
* `toCurrent` (default): The window moves to the current desktop when it's summoned
* `any`: We don't care what desktop the window is on. We'll go to the desktop the window is on when we summon it.
* `onCurrent`: We'll only try to summon the MRU window on this desktop when summoning a window.
* When combined with `name`, if there's a window matching `name`, we'll move it to this desktop.
* If there's not a window on this desktop, and `name` is omitted, then we'll make a new window.
`quakeMode` was also updated to use `toCurrent` behavior by default.

## Detailed Description of the Pull Request / Additional comments
S/O to https://github.com/microsoft/PowerToys, who graciously let us use `VirtualDesktopUtils` for figuring out what desktop is the current desktop. Yea, that's all we needed that entire file for. No, there isn't an API for this (_surprised-pikachu.png_)
## Validation Steps Performed
Played with this for a while, and it's amazing.
Adds support for two new actions:
* `globalSummon`, which can be used to activate a window using a _global_ (READ: OS-level) hotkey.
- accepts an optional `name` argument. When provided, this will attempt to summon with the given name. When omitted, we'll try to summon the most recent window.
* `quakeMode` which is `globalSummon` for the `_quake` window.
These actions are stored in the actions array, but are read by the `WindowsTerminal` level and bound to the OS in `IslandWindow`. The monarch registers for these keybindings with the OS. When one is pressed, the monarch will recieve a `WM_HOTKEY` message. It'll use that to look up the corresponding action args. It'll use those to try and summon the right window.

## Summary of the Pull Request
We don't want it acting as the "most recent window" for windowing behavior.
The most recent window should always be some other window.
This is being made as an atomic commit because we're probably 50% sure on this
one. Maybe people do want new tabs to open up in the quake window! If they're
running from the commandline, that's easy. If they're running from the shell
context menu, that's **H**ard / impossible currently. $20 someone asks for
that if we ship this. That of course might just fall into "explorer context
menu settings" though.

## Validation Steps Performed
Played with this, it works exactly as you'd think.
## Summary of the Pull Request
Brace yourselves, it's finally here. This PR does the dirty work of splitting the monolithic `TermControl` into three components. These components are:
* `ControlCore`: This encapsulates the `Terminal` instance, the `DxEngine` and `Renderer`, and the `Connection`. This is intended to everything that someone might need to stand up a terminal instance in a control, but without any regard for how the UX works.
* `ControlInteractivity`: This is a wrapper for the `ControlCore`, which holds the logic for things like double-click, right click copy/paste, selection, etc. This is intended to be a UI framework-independent abstraction. The methods this layer exposes can be called the same from both the WinUI TermControl and the WPF control.
* `TermControl`: This is the UWP control. It's got a Core and Interactivity inside it, which it uses for the actual logic of the terminal itself. TermControl's main responsibility is now
By splitting into smaller pieces, it will enable us to
* write unit tests for the `Core` and `Interactivity` bits, which we desparately need
* Combine `ControlCore` and `ControlInteractivity` in an out-of-proc core process in the future, to enable tab tearout.
However, we're not doing that work quite yet. There's still lots of work to be done to enable that, thought this is likely the biggest portion.
Ideally, this would just be methods moved wholesale from one file to another. Unfortunately, there are a bunch of cases where that didn't work as well as expected. Especially when trying to better enforce the boundary between the classes.
We've got a couple tests here that I've added. These are partially examples, and partially things I ran into while implementing this. A bunch of things from #7001 can go in now that we have this.
This PR is gonna be a huge pain to review - 38 files with 3,730 additions and 1,661 deletions is nothing to scoff at. It will also conflict 100% with anything that's targeting `TermControl`. I'm hoping we can review this over the course of the next week and just be done with it, and leave plenty of runway for 1.9 bugs in post.

## Detailed Description of the Pull Request / Additional comments
* I don't love the names `ControlCore` and `ControlInteractivity`. Open to other names.
* I added a `ICoreState` interface for "properties that come from the `ControlCore`, but consumers of the `TermControl` need to know". In the future, these will all need to be handled specially, because they might involve an RPC call to retrieve the info from the core (or cache it) in the window process.
* I've added more `EventArgs` to make more events proper `TypedEvent`s.
* I've changed how the TerminalApp layer requests updated TaskbarProgress state. It doesn't need to pump TermControl to raise a new event anymore.
* ~~Something that snuck into this branch in the very long history is the switch to `DCompositionCreateSurfaceHandle` for the `DxEngine`. @miniksa wrote this originally in 30b8335, I'm just finally committing it here. We'll need that in the future for the out-of-proc stuff.~~
* I reverted this in c113b65d9. We can revert _that_ commit when we want to come back to it.
* I've changed the acrylic handler a decent amount. But added tests!
* All the `ThrottledFunc` things are left in `TermControl`. Some might be able to move down into core/interactivity, but once we figure out how to use a different kind of Dispatcher (because a UI thread won't necessarily exist for those components).
* I've undoubtably messed up the merging of the locking around the appearance config stuff recently

## Summary of the Pull Request
This PR adds support for renaming windows.
It does so through two new actions:
* `renameWindow` takes a `name` parameter, and attempts to set the window's name
to the provided name. This is useful if you always want to hit <kbd>F3</kbd>
and rename a window to "foo" (READ: probably not that useful)
* `openWindowRenamer` is more interesting: it opens a `TeachingTip` with a
`TextBox`. When the user hits Ok, it'll request a rename for the provided
value. This lets the user pick a new name for the window at runtime.
In both cases, if there's already a window with that name, then the monarch will
reject the rename, and pop a `Toast` in the window informing the user that the
rename failed. Nifty!

## Validation Steps Performed
I've been playing with
```json
{ "keys": "f1", "command": "identifyWindow" },
{ "keys": "f2", "command": "identifyWindows" },
{ "keys": "f3", "command": "openWindowRenamer" },
{ "keys": "f4", "command": { "action": "renameWindow", "name": "foo" } },
{ "keys": "f5", "command": { "action": "renameWindow", "name": "bar" } },
```
and they seem to work as expected
## Summary of the Pull Request
This is a follow up to #9300. Now that we have names on our windows, it would be nice to see who is named what. So this adds two actions:
* `identifyWindow`: This action will pop up a little toast (#8592) displaying the name and ID of the window, and is bound by default.
* `identifyWindows`: This action will request that ALL windows pop up that toast. This is meant to feel like the "Identify" button on the Windows display settings. However, sometimes, it's wonky.
That's being tracked upstream on https://github.com/microsoft/microsoft-ui-xaml/issues/4382
Because it's so wonky, we won't bind that by default. Maybe if we get that fixed, then we'll change the default binding from `identifyWindow` to `identifyWindows`

## Detailed Description of the Pull Request / Additional comments
You may note that there are some macros to make interacting with lots and lots of actions easier. There's a lot of boilerplate whenever you need to make a new action, so I thought: "Can we make that easier?"
Turns out you can make it a _LOT_ easier, but that work is still behind another PR after this one. Get excited
This finishes the implementation of `--window` to also accept a string
as the "name" of the window. So you can say
```sh
wt -w foo new-tab
wt -w foo split-pane
```
and have both those commands execute in the same window, the one named
"foo". This is just slightly more ergonomic than manually using the IDs
of windows. In the future, I'll be working on renaming windows, and
displaying these names.

Before this PR, I think we didn't actually properly support assigning
the id with `wt -w 12345`. If `12345` didn't exist, it would make a new
window, but just assign it the next id, not assign it 12345.

## Validation Steps Performed
Ran tests
Messed with naming windows, working as expected.
Closes https://github.com/microsoft/terminal/projects/5#card-51431478
Adds support for the `windowingBehavior` global setting. This setting
controls how mutiple instances of `wt` behave in the absence of the `-w`
parameter. This setting has three values:
* `"useNew"`: (default) Multiple `wt` invocations (without the `-w`
param) always create new windows.
* `"useAnyExisting"`: When starting a new `wt`, we'll instead default to
any existing windows. `wt -w -1` will still create new windows.
* `"useExisting"`: Similar to `useAnyExisting`, but limits to
windows on the current desktop.
The IVirtualDesktopManager interface is _very_ limited. Hence why we
have to track the HWNDs manually, and ask if they're on the current
desktop.

## Summary of the Pull Request
**If you're reading this PR and haven't signed off on #8135, go there first.**
This provides the basic parts of the implementation of #4472. Namely:
* We add support for the `--window,-w <window-id>` argument to `wt.exe`, to allow a commandline to be given to another window.
* If `window-id` is `0`, run the given commands in _the current window_.
* If `window-id` is a negative number, run the commands in a _new_ Terminal window.
* If `window-id` is the ID of an existing window, then run the commandline in that window.
* If `window-id` is _not_ the ID of an existing window, create a new window. That window will be assigned the ID provided in the commandline. The provided subcommands will be run in that new window.
* If `window-id` is omitted, then create a new window.

## Detailed Description of the Pull Request / Additional comments
Note that `wt -w 1 -d c:\foo cmd.exe` does work, by causing window 1 to change
There are limitations, and there are plenty of things to work on in the future:
* [ ] We don't support names for windows yet
* [ ] We don't support window glomming by default, or a setting to configure what happens when `-w` is omitted. I thought it best to lay the groundwork first, then come back to that.
* [ ] `-w 0` currently just uses the "last activated" window, not "the current". There's more follow-up work to try and smartly find the actual window we're being called from.
* [ ] Basically anything else that's listed in projects/5.
I'm cutting this PR where it currently is, because this is already a huge PR. I believe the remaining tasks will all be easier to land, once this is in.
## Validation Steps Performed
I've been creating windows, and closing them, and running cmdlines for a while now. I'm gonna keep doing that while the PR is open, till no bugs remain.
# TODOs
* [x] There are a bunch of `GetID`, `GetPID` calls that aren't try/caught 😬
- [x] `Monarch.cpp`
- [x] `Peasant.cpp`
- [x] `WindowManager.cpp`
- [x] `AppHost.cpp`
* [x] If the monarch gets hung, then _you can't launch any Terminals_ 😨 We should handle this gracefully.
- Proposed idea: give the Monarch some time to respond to a proposal for a commandline. If there's no response in that timeframe, this window is now a _hermit_, outside of society entirely. It can't be elected Monarch. It can't receive command lines. It has no ID.
- Could we gracefully recover from such a state? maybe, probably not though.
- Same deal if a peasant hangs, it could end up hanging the monarch, right? Like if you do `wt -w 2`, and `2` is hung, then does the monarch get hung waiting on the hung peasant?
- After talking with @miniksa, **we're gonna punt this from the initial implementation**. If people legit hit this in the wild, we'll fix it then.
Adds a `Microsoft.Terminal.Remoting.dll` to our solution. This DLL will
be responsible for all the Monarch/Peasant work that's been described in
#7240 & #8135.
This PR does _not_ implement the Monarch/Peasant architecture in any
significant way. The goal of this PR is to just to establish the project
layout, and the most basic connections. This should make reviewing the
actual meat of the implementation (in a later PR) easier. It will also
give us the opportunity to include some of the basic weird things we're
doing (with `CoRegisterClass`) in the Terminal _now_, and get them
selfhosted, before building on them too much.
This PR does have windows registering the `Monarch` class with COM. When
windows are created, they'll as the Monarch if they should create a new
window or not. In this PR, the Monarch will always reply "yes, please
make a new window".
Similar to other projects in our solution, we're adding 3 projects here:
* `Microsoft.Terminal.Remoting.lib`: the actual implementation, as a
static lib.
* `Microsoft.Terminal.Remoting.dll`: The implementation linked as a DLL,
for use in `WindowsTerminal.exe`.
* `Remoting.UnitTests.dll`: A unit test dll that links with the static
lib.
There are plenty of TODOs scattered about the code. Clearly, most of
this isn't implemented yet, but I do have more WIP branches. I'm using
[`projects/5`](https://github.com/microsoft/terminal/projects/5) as my
notation for TODOs that are too small for an issue, but are part of the
whole Process Model 2.0 work.
