I was asked to “disable change float (undock) tab on mouse double click”. I added this feature the last summer, copying the default Visual Studio 2010 behavior. But accidental double click on a tab is a problem (e.g. read Turn off double-click undock in VS2010, How To Disable Floating Windows? and How to disable floating tabs in Visual Studio 2010).
I’m planning to disable floating on double click in the next Tabs Studio release. For those who find this feature useful, I can reintroduce it as a separate add-in. Please, comment if you feel pro or against this feature.
