So can we now more easily have separators in the toolviews submenu? And
also radio-buttons so its more obvious that you can select one from a list
of x between two separators? There's a bugreport open for that, but I
didn't want to remove the action collection when I looked at the code back
then. Mostly this was because I couldn't see what other side-effects it
might have if I drop the collection.

The plan was to allow merging similar to QMainWindows implementation for
toolviews/dockwidgets. That is allow splitting of the left/right/top/bottom
area with splitters. And inside these again have a new tabbar (i.e. our
toolbuttons). And obviously at that point we will need drag'n'drop support
too for the toolviews.
