My old MBP has the old-style trackpad (separate button) so only supports 2-finger gestures. When I got my rMBP I'd forgotten that it supports 3- and 4-finger too - until I investigated why it was doing seemingly random things, like Mission Control suddenly appearing. 
Now I've got them figured out I'm loving them, makes things so much easier, but there's one thing I don't like. When using 4-finger left/right swipe to switch desktops/full-screen apps, is there anyway to make it cyclical? By this I mean if, for example, you have 4 desktops and you are on 1, swiping 3 times right-to-left gets you to 4, but to get back to 1 you have to swipe 3 times left-to-right. Anyway to make it got from 4 to 1 by swiping right-to-left one more time?
