I've been trying out Lion GM and everything else is great. However, I just can't get use to it's weird multitouch changes. I want to be able to: 1. Use 4-finger down swipe to "Show Desktop" 2. 3-finger forward/backward in apps (Chrome, FF) 3. 4-finger down (NOT up) swipe for showing all windows. 3. Showing every window in expose (I don't want some windows to cover others). Anyway I can do these things?
