Show desktop overview when switching desktop with the active window

[Rüdiger Kupper]

When switching desktops with moving the active window (CTRL-SHIFT-ALT-arrowkeys), the small window giving an overview over the desktops is not shown. When switching without moving the active window, this small window is shown in the middle of the screen.
The desktop overview should be shown, too, when switching with moving the active window.
This is especially disturbing, when no other windows are present on the desktops, since then the user receives no feedback at all whether switching was successful (since source and target desktops look identical).
