Description Andres Betts 2020-10-26 20:40:02 UTC 
SUMMARY
In our current version, if System Settings has the Present Windows effect enabled by using a screen corner, the effect works on all windows except when there is only one window.

When there is only one window in the desktop, present windows does not activate.

I feel this behavior should change. There should be an activation even though there is only 1 window on the desktop and even though there are no windows on the desktop.

The reason being because by not activating the effect, we break the predictability of the effect. A user may want to activate it to just see if there are any windows in any screen that are selectable. In large screen arrays, this may be necessary.

At the same time, even if there are no windows on the desktop, the activation should still happen. The background should still turn darker and probably show a message saying "No windows present". That way the user confirms that there are no windows anywhere to present.
