When the floating tab window is open, clicking on another application’s window leaves the floating tab window still floating in front of the other application.
This occasionally catches me up when the other application has a window that is completely hidden by the floating tab window so that I don’t see it.
On MacOS at least it’s possible to find it by right clicking on the application in the Dock and selecting “Show all windows”, but with the window completely hidden, I may be unaware or forgetful of its very existence.
The Floating window would get in the way less often if only floated in front of other 010 Editor windows.
