Ultimate Window Management Machine

Witch fills the gap between Exposé and Dock Exposé to make it easy to switch to any open window in any open application all from the keyboard. You can customize the look and feel to make it work for you as well. This is also a perfect switchers utility for users who come from Windows and expect Cmd/Alt Tab to switch between any window and Witch brings that to the Mac in the most make like way! Highly recommended!
