First menu item in new "app menu" is confusing
The first menu item in the new application top bar menu (where the app menu used to be) focuses the application's current window. But since this menu is only displayed when the application is already focused, that means this menu item does nothing. Oops?
Instead of using the exact same menu here as for right-clicking on the dash icons, it probably makes sense to trim off the top menu item instead, since it's not useful. I suppose it's kinda useful for showing the window title, but then it shouldn't be clickable.
