I’ve had this tool laying around in my to-do folder for a while now, and today seemed like a good day to take a look at it.
Office Tab brings the tabbed interface from IE, Firefox and Chrome to the Office suite. Instead of the user interface where each document is a separate window, you’re basically returning to the old interface from I think Office XP, where each application within the suite has one window, and there are multiple documents within that window.
The Free version allows you to include tabs in Word, Excel and PowerPoint. If you want tabs in Project or Visio, you’ll need the Professional or Enterprise version. A complete comparison of the versions is found here.
Office Tab 7 is available in 32-bit and 64-bit versions, and supports Office 2003, 2007 and 2010.
