How do you interface with a lot of the things that make up the OS X GUI (in particular, Mission Control)? Apple doesn't seem terribly open to developers trying to mess with their stuff, so I can't seem to find a public API to it anywhere. Really, I just want to tweak a few things to my own preference.
I know it can't be impossible; I've seen third-party apps switch a thing or two around.
Thanks for any help!
