Highlight window previews for open applications using Dash
As a way to distinguish application window thumbnails from each other in the overview, especially when the number of windows gets quite high, we could tie a hover/focus effect on windows with hovering or focusing on items in the dash for that corresponding application, here's a quick-and-dirty concept:
I.e. when the item has focus/hover the corresponding windows have the border highlight.
This is a small visual thing to make finding application windows slightly easier, but it would be the default for all open apps that hovering on the dash item highlights the window in a subtle way in the overview.
