Switching Spaces with the mouse!
It is already possible to switch from one space to another using the mouse if you are also bringing a window with you. If you just want to switch however, you have to use the keyboard (or F8). What if you could just bring the mouse to the edge and it would switch to the other space like a dual display setup. It is very easy to make this possible with an application called Warp. I thought that was cool at first, but it just got too easy and I ended switching accidently. The feature that made it worthwhile is the modifier. You can decide that you need to hold down a modifier like "Command" to switch. I think this makes switching from a space to another much easier. The best is that the application doesn't run in the background, it is totally integrated to System Preferences. You can learn more about Warp or download it here on MacUpdate.
