Comment 28 for bug 1573031

Just additional idea. Is there any way to create drop-down list of all other toolbars (or at least the most important one), which could be selected and displayed over the current single-toolbar in single-toolbar mode? Something I suggested in https://bugs.documentfoundation.org/show_bug.cgi?id=80752 but implementation does not need to include the "line" above single-toolbar with toolbar names, yet simple drop-down list?
