Think about it... if the window is maximized, this region lies outside the window and is unreachable.

Doug,

A great idea, but how would this work with dual/milti monitors? Or, even, with the "grid" plugin from compiz, (allows you to square off windows with relative ease CTRL+ALT+NUMPAD1 = bottom left, CTRL+ALT+NUMPAD3 = bottom right, etc.).

Certainly an "outside" invisible area would overlap windows, and would have to be considered in implementation.
