- The aim of this is to more clearly visualize how the timerange of the cell selected in the swimlane relates to the time span shown in the charts. - The most important change is that the vertical date axis ticks no longer are randomly positioned by d3. Instead they are aligned with the cell interval of the swimlane. This way, the date information shown in the swimlane tooltip will always align with the date tick shown left of the emphasized area in the chart. - The highlighted area now features a gray rounded border to resemble the styling of the selected cell in the swimlane. - The chart also fixes where to long chart headers would wrap the "View" link to a new line. - The x/y axis labels blackness has been reduced to reduce emphasis on the labels.
