Sometimes it is nice to see your entire desktop, for example, for opening programs. There is now a new window that is your entire desktop :)
Because this doesn't work for some people (such as some Laptops and people with Windows 7) I autodetect if it works for you at the start and there's a little bar in the menu that should tell you whether or not you have that functionality. If anyone's program is crashing though let me know and I can make a way to manually disable it if that test isn't working for you.
I'm told this is the same API that BigScreen and Virtual Desktop use, and after lots of optimization it is running very quickly for me. So enjoy :)
