I’ve created the default toolbar for Tabs Studio that includes Options, Add-in manager, Previously selected tab, Open corresponding file, Tabs window and About commands:

This toolbar is also available in SSMS (though you need to manually make it visible):

I plan to make the toolbar available in Visual Studio 2010 closer to its release date.
