7stacks is an easy to use, free app that lets Windows 7 , Vista and XP users have "stacks" of icons in their Taskbar or QuickLaunch Toolbar. By using stacks, users can reduce icon clutter, and combine a group of related icons into a single icon. For instance, if you use application suites such as Microsoft Office, OpenOffice, or Adobe CS4, you can have all the suite's icons combined into one icon!
