I'd agree that this is a bit of a UX regression. Buttons for commonly used functions are moved into a menu where they can get lost and are just less reachable overall.
Also I see that it's supposed to be a menu bar (in which case the dropdown arrows aren't really used by convention), but there's only one menu so it kinda feels superfluous. At first I actually thought it was a glitched or misplaced double title bar (I've seen this happen with windows from other plugins), which is why it didn't even occur to me that it could be clickable.
