Notice some issues with the bar menus...
If you populate a drop-down menu (Menubar -> BarPopupButton -> More BarButton's than can fit on screen) with more menu items than it can fit on the screen, it causes the menu to instantly close after popup, becoming unusable.
Alternatively, if the setup is Menubar -> BarPopupButton -> BarPopupButton -> too large BarButton list, then instead the menu just extends beyond the bound of the screen.
Ideally if the menu is too large, it should add up and down buttons at the top and bottom of the menu to allow navigation (either mouse-over or click-and hold). An option to specify the maximum size of the menu before this happens might also be useful.
