3holelover re my comment about the plane image control surfaces clue, "Airbus will also display that on the ECAM FLT CTL page. (but you all knew that, right?... Is the suggestion for a separate screen always displaying this?"
Yup. It's there when you need it. Otherwise ignore it. If it also included an arrow to show AoA that would kill two birds on one separate display that is ignored most of the time. "Mousing" through a list of display menus when in the situation the plane fell into is not feasible - even if it is one push button beside the FD display.
