Gnome Do - Launchy for Linux!!!

Okay, so one of my huge regrets of switching to Linux was that I had no application launcher like Launchy - which is just awesome in Windows. You just press Alt+Spacebar and a little window appears and you type in whatever program (or action/file/location...etc.) you want to launch and it pulls it up. Awesome stuff.

Well, I just heard about Gnome Do, a program similar to Launchy, but meant to be run in Gnome (a linux environment - note that it apparently also works with KDE and some other environments as well).

Pretty simple stuff really. Used these instructions.
