Spaces really needs some attention. It makes me much more productive overall, but it really feels like it's been forgotten. Beyond just making it less buggy, some simple things would make a huge difference, like being able to rename spaces, and not only showing the name of the space when you hover over it.

Edit: Thanks for the tip about killing the dock to get the keyboard shortcuts working. That was driving me mad. Do you have to do that every restart, or will those just work now?
