Arrange strip
Taskbar numbers on cards
Each card in the Arrange strip shows a small number before its name. It is the place of the window in the taskbar row on that desktop. This is the same order that Win+number goes through. The numbers show in both views, in the hover strip and in Win+Alt+A.
Small labels in the By monitor view are now 12 px, like all other text.
LayoutKeeper

A few seconds after Explorer restarts, LayoutKeeper puts the saved order of every app back on the current desktop.
