Windows only: You don't want to watch YouTube videos in the browser window or waste your screen space by going full screen. What to do? Break it out into a separate viewing window. DetachVideo is a simple stand alone application. You run it, it sits in your system tray and from there out whenever you put your mouse over an embedded video and press F12 the video will break out of the browser into its own little window. The hot key can be changed from F12 if that conflicts with your current hot key setup. DetachVideo is freeware, Windows only.
