I’ve been using this great utility for a few months now, and it’s installed on every one of my computers now. If you’re using Windows and find yourself inundated with applications in your taskbar you should give it a shot. I started using it just to rearrange running applications but I just installed the latest version (2.0) and it has some cool grouping options that are going to come in handy.
Oh, and it’s free. The author does take donations, however.
