Word Addin tab is a plugin for Word 2007/2010 that creates tabs in Word for multiple documents. If Multiple multiple MS Word files are opened in Windows 7, the files will default to arrange vertically in the Taskbar like that:

Or horizontally lie down in the Taskbar as the below picture shows:

Word Addin Tabs integrates MS Word with “tabs” function. At this point, it helps the use of Word more convenient as IE.

Word Addin Tabs realizes most of the functions of “IE Tabs” in MS Word. Also Tabs can be closed easily by clicking the “Add-ins” menu and pressing the “Tabs” button, and then the “tabs” function will be closed. Getting tabs in Office is what i expected from Office 2010, may be when it comes out of beta we wont require this wonderful plugin.
