If you were wondering how the trusty Expose feature in your OS X will work once you’ve gone all “virtual desktop”, take a look at the video. Leopard’s going to allow you to Expose while in Spaces, so you can drag windows from one desktop to the other with minimal fuss.
The only problem we have is that the windows are already small enough in regular Expose, and will get even smaller when Exposing in Spaces. The only way to see the name of the Window is to mouse over it, which could get tiring when you’re mousing over 5 different Textedit windows to see which one is the one you want to move to another virtual desktop. Can Apple please add the window name to ALL applications?
