It does. In the videos I watched of Charline Poirier's user test two
weeks ago, of the eight out of ten people who could find the hidden
menus at all, seven of them discovered the menus while mousing over the
close/minimize/unmaximize buttons in a maximized window.

They then concluded that the way to access menus was to hover over the
close/minimize/unmaximize buttons, and then move sideways. This was very
slow, and didn't work at all in unmaximized windows.

People were much faster at using LibreOffice's menus, which are not yet
integrated into the global menu bar by default.
