Are there any programs that make alt-tab better? I have a desktop with ubuntu on it and a laptop with vista on it and this iMac is in the other room. The alt-tab on ubuntu and vista is so much better than the OS X one. I'm confused as to the use of alt+tab on OS X. I figured out it changes the bar at the top to a different application and all applications which show up seem to only be ones which do have a change to the menubar but sometimes i'll alt-tab to something and it'll come to the front and sometimes it wont and sometimes it'll show me programs that i don't even think are open. Is there a program or add-on which makes alt+tab work better or a guide on how to make the most of it?
