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 2013, 2010, 2007, 2003 and Office 365 (Word, Excel, PowerPoint, Publisher, Access, Project and Visio)
Main Features:
- 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.

Save All in One Click
A key advantage of Office Tab is that you can save time by consolidating your actions! For example, if you have opened multiple files, you do not have to save and close them individually just click Save All from the Context menu and all your files are saved. Want to close all opened files? Simply select Close All and all your files will be closed.

Manage Documents in Groups
In Office Tab, you can add a saved Microsoft Office file to a group. You can quickly open a group of documents or a group of Excel files and so on. With this Favorites Group feature, you can apply the following operations to a group of documents in Microsoft Office applications easily.

Rename Files Easily
You do not have to open the Save As dialog to rename a file. Just click Rename on the Context Menu in the tab and enter the new file name its that simple! If you want to save the file in another folder, select Save As from the Context Menu.

Displays Full File Name
If a file name is long, typically, the Windows taskbar displays only a small part of it, which is often a problem. However, with Office Tab installed, you will able to see the entire file name on the Tab Bar, no matter how long it is.

Useful Context Menu
Right-click on a tab or Tab Bar to access the tab/tab bar context menu. Office Tab also combines some common command items in Microsoft Office, letting you access those items more quickly.

Easy-to-use
The tabbed interface allows you to open multiple documents in a single window. Each document appears as a new tab within the window (not a new window) and can be accessed with one click. This feature improves your efficiency when working with Microsoft Office programs (Word, Excel, PowerPoint, Project, Publisher, Access and Visio).

High Performance
Office Tab is based on the standard Microsoft Office Add-in Technology. It does not impact the performance of the standard application and has an extremely small file size.

Move Tabs
Tabs can be moved easily by dragging. You can switch between tabs using the mouse or you can activate a tab by pressing Alt + N (N being the tab order 1, 2, 3).

Customize Tab Appearance
The colors of the tabs and the Tab Bar are customizable. There are 11 styles for you to choose from.
