Mountain Lion Conflict?!?!

I downloaded the app on Mountain Lion, and now Mission Control, Notification Center, and some gestures are disabled! It looks nice, but not worth $2.99!
Also I have the Retina 15" MacBook Pro, and I do NOT like how choppy the graphics look when doing something like using the Visualizer in iTunes, and even when the system is using the NVidia GPU it is still quite choppy, and one last thing… Close the app if youre about to game, this app doesnt pause… It contiues running in the background while the game is running, which in turn causes the game to constantly drop frame rates! So I hoped this helped before you buy this app!
