To turn up the volume just now required three taps: one to wake it up (why would a keyboard have to be activated!?), one to open up the "normal" function menu (why is it it collapsed when the app doesn't have any of its own buttons!?), and one to press the volume key. It would have been one press on a real keyboard.
Plus, the touch target on that "expand" widget is tiny (which wouldn't be so bad if it was an actual, tactile BUTTON)
