Mission Control / Expose Clone W7 is a simple "expose" like tool with some of the features of "mission control" and a couple of more. Like "expose" it arranges live thumbnails of all desktop windows arranged to fit on a single monitor screen. Like "mission control" it arranges the thumbnails in "piles," with all windows of a single application in a pile. Also allows grouping "similar" applications (i.e., all web browsers) into one pile.
