Alt-Tabbing, Perfected.

Adri recommends a freeware app called Witch that takes application switching to the satisfying conclusion we've all been waiting for. Now you can both Apple-Tab (normal app switching) and Alt-Tab (window switching) in OSX. Coupled with Exposé and LaunchBar's active program switcher (invoke LaunchBar, then press Down Arrow), one finds little left to be desired in this field. Having Witch around marries what was once an arguably superior element of the Windows OS experience (convenient to have everything in separate windows, but also clunky to manage [especially without Exposé]) with the overall elegance of Mac OSX, producing a simple, and perfect, solution. Two alt-tabs are better than one. Apple should buy out and implement this into Tiger if its not too late.

Now if only someone could find a way to do a system-wide Zoom keystroke (green button) because there isn't one as far as I know. The one in Witch doesn't seem to work on eDonkey.
