Is it overly geeky to want to rearrange the order of the applications in your Windows taskbar?
I’ve installed [Taskbar Shuffle](http://www.freewebs.com/nerdcave/taskbarshuffle.htm) to do this. You simply drag and drop to arrange their ordering.
On my PC at work, I tend to have many windows open at the same time – email, todo list, multiple telnet sessions, multiple browsers, Framemaker, Visio, multiple Explorer windows, etc. Keeping related windows together helps me switch between tasks and work more efficiently.
Taskbar Shuffle also lets you rearrange system tray icons, but I’ve never bothered doing that.
