The top bar on the root screen has always seemed really clunky (inconsistent, non-intuitive, etc) to me.
With the new update we finally have a proper menu that is available everywhere and works (and looks) nice. With a few more features (settings for example) I can't understand what the purpose of the top menu is at all. Why not just use the side menu on the left? On root screen you could include a little arrow letting the user know to swipe to open the menu to provide a little direction.
