It would be cool if you could define a specific area at the top of the screen that triggers the appearance of the Multiplicity menu/control bar (ex just the top middle, just the top left, etc).  So many times, trying to close or move a (relatively) fullscreen window (or window positioned at the top of the screen) unintentionally brings up the Multiplicity control bar.  Being able to define a limited trigger area at the top of the screen would be a great help on that.  Even better, the ability to set it to the left or right sides of the screen as an alternative (for those just in KVM mode, like me).
