Hmm, for 2) I managed to get a different display by selecting the mixer screen from some key. In there I got to the menus and managed to put the toolbar back into the Arrange view…
Still, how about if I had removed the toolbar from all the views? Maybe there should be a key shortcut to get to the GUI edit menus at least, so there would be no possibility of a “dead end”?
Where is this GUI info kept? I didn’t see any files that looked like it.
