Tray It!
A nice little program I discovered at work, Tray It! lets you minimize any window to the system tray. Its free, small, unobstrusive, and in my case, ridiculously useful. There are a few programs that offer the same abilities, but some of them appear to be shareware or demoware… and if they’re as easy to use as Tray It! is (all you have to do is hold control while minimizing), then I would be surprised. Congrats to the Tray It! team for a job well done.
