I feel that many of the features aren't implemented system wide, and there aren't many customizable options. From gestures to features like dictionary. I feel features should be more tightly nit. For example, gestures like two finger swipe for navigation aren't even enabled in Finder, which is appalling. I also feel that there should be more customizable options, for example I feel we should be able to have the card sliding animation when we have three finger swipe enabled. if they implemented Options, we wouldn't have so many complainers like me who don't like some new features. Why not give us the freedom of choice?
