Featured Windows Download: Add tabs to any program with WinTabber

Windows only: Freeware app WinTabber can add tabs to any program for easy grouping. Not only can WinTabber group multiple instances of the same program into tabs, but it can also group different programs together into tabs (as shown in the screenshot). Its possible uses abound, but grouping your applications based on purpose is one idea with a lot of potential. For example, you could create two groups of tabs: one group for work-related applications and one group of tabs for your non-work-related apps. WinTabber is a free download for Windows only.
