I looked in the system preferences menu, and it seems like besides changing the right-click option, you cannot customize what the 3/4 finger swipes do. For example: I'd like to customize the 4-finger swipe to switch spaces instead of switching applications. Is there any software out there that allows you to customize the gestures? I've been using Firefox w/ the Firegestures add-on and that seems like a simple and brilliant program. Anything like it that works with the touchpad on the mac? Also, when you are in expose, and the windows are tiled, can you close windows from the expose view, instead of selecting the window to bring it to the front, and then clicking the ''x"?
