Next week, Ubuntu developers will be discussing the possibility of adding a desktop focused version of the new Unity interface to the normal build of Ubuntu. This edition would have these changes among other possible improvements:
-Would be movable to any edge of the screen per user preference.
-Normal style floating windows, with window controls in the windows.
-Home screen turned into a drop down menu with search and program access.
(Please do note that this is only a plan/discussion right now. But Mark Shuttleworth is assigned to the blueprint.)
