Office Tab

Tabbed Browsing, Editing, and Managing of Documents in Microsoft Office 2003, 2007, 2010 and 2013

With the standard versions of Microsoft® Office, you cannot view and edit multiple files within a single tabbed window. Office Tab changes this by introducing a tabbed user interface—as seen in web browsers such as Internet Explorer® 8, Firefox and Google Chrome—in Microsoft Office 2003, 2007, 2010 and 2013 (Word, Excel®, PowerPoint®, Publisher®, Access®, Project and Visio®). New features in Office Tab 9.60

Open, read, edit, and manage multiple Office documents in a single tabbed window.
Minimize the number of windows you open at the same time.
Save and close all Office documents with one click.
Based on Microsoft Office add-in technology.
