It would be very convenient if the button to see the battlefield was not obstructed by the action menu for the unit in square #9. If you happen to be viewing a graveyard or your file, it's impossible to return back to the battlefield view and you can't even see the choices for the unit who is obstructing the button.
This is an extreme case when you're looking at a graveyard/file and you click to return back to the battlefield view, but that units turn comes up just as you click and you end up selecting Move or Standby instead of a vital buff or other action skill. (I seriously just lost a game because of that)
