This CL is adding a minimize function for clicks on launcher items if only a single item (already active) is associated with it. This is done to avoid that the user clicks and nothing happens (and people expect it to do that). The feature is guarded by a flag.

If the minimize action is not wanted, we use a bouncing animation which gives the user at least some feedback that he has done something.
