Is there a list somewhere that shows how multi-touch trackpad gestures for various actions differ between Snow Leopard and Mountain Lion? I think it will make transitions for people coming from SL easy.
I agree with TexasChemE.
I will end up setting everything the way I want it with BetterTouchTool anyway. I think it is ridiculous that Apple calls new gestures features. That is just a setting that anybody can change to whatever suits best.
