Tabs Studio supports several IDEs (VS 2010/2008/2005, SSMS 2008/2005, VS LightSwitch and PowerBuilder .NET 12.0), so you may want to revert to default tabs in some of these products. Usually you can disable Tabs Studio going to host’s Add-in Manager dialog, but not in SQL Server Management Studio. Specifically for SSMS that lacks built-in Add-in Manager, I’ve added the new option to disable Tabs Studio:
Disable Tabs Studio option
When checked, Tabs Studio tabs are not visible, but Tabs Studio toolbar is still available and you can enable Tabs Studio back if needed.

Thank You! I love Tabs Studio in VS 2010, but not so much in SQL Server Management Studio. This makes it easy to get just what I want!
