.NET Style Tabbed Workspace Groups

Command Bars allows you to easily create .NET style tabbed workspace groupings.  You have the ability to group tabs vertically or horizontally within the tab workspace.  Tabs can easily be moved from one group to another by a drag-and-drop or via code.  You can easily add functionality for the user to create a new horizontal/vertical group and move a tab to the previous/next group simply by adding a control in your Command Bar.
