i miss the option "suppress tabs" in preference "canvas only settings", in full screen everything should focus on one goal - the painting. Maybe add a shortcut to switch tabs in fullscreen mode
i guess, you cant hide tabs in fullscreen mode, because of the QT framework?
Right... You can select subwindow instead of tabbed mode, but on OSX that has the disadvantage that Qt's subwindow titlebar remains visible! There is no way to hack around that that isn't incredibly fragile, I'm afraid. Worse, Qt doesn't do a whole lot of development on the QMdiArea class anymore, so we should have to rewrite it ourselves. I'd love to do that, but I'm already spending all my waking time working Krita.
