Re the para door, when I left the programme they (Airbus) still hadn't figured out how the step (hinged part of the fairing) was going to retract. It should be the first action as the door is unlatched otherwise its going to be a blockage if the door is to be cleared as an emergency exit. The last idea I saw was you opened the door and then unlatched and lowered the step. NO NO NO. I even suggested they should look at the drag penalty of flying with it permanently down to avoid the problem
That said, with the door open and the air deflectors out (they may not be needed, so it might only appear on the prototypes) I reckon the step could be a nice place for sitting out on patio furniture.
