GroupBar
If you’re looking for an alternative for managing your windows, GroupBar, a free application designed for Windows XP is a good solution. This application makes it easy to group applications together.gHacks gives an example of grouping Firefox, an email client, and your instant messenger together. After they’ve been grouped together they can be started and minimized from the sidebar at once. This would be useful for those programs you use everyday like the ones mentioned, and the ones that you always use together. Groupbar doesn’t have to be installed, rather just download it and start GroupBar.exe.
