another two:

* when you fullscreen a window, there's a white (sometimes black) bar where the menu bar used to be * app switcher changes monitor depending on the monitor you last used the dock (which makes no actual sense).

That first one happens if an app is built with an SDK older than 10.9.

It's "better" in so much as I can full screen two things now instead of looking at a useless monitor full of fake fabric.

I also have two spaces and things don't really quite work right. I'm not quite sure how to make it work better, but it almost never does what I mean right now.
