Feature request (usablity): Closing all opened instrument (windows)

If you have ie. many instruments opened (instrument window shown) ... additionally maybe also the song editor opened, BB Editor, Fx-Mixer, ... and maybe opened effect windows it takes some time to close all "unnecessary" window again...

It would be nice if you would open the context menue of a opened window (right-click windows title bar) and then from there you can execute "Close all windows but this" ... or also via a shortcut - i like this feature a lot on using other software (not dedicated to DAWs - dont know if other DAWs have this feature)
