On 747, I would prefer if the door mode selection box was designed differently. There's really no place for the safety pin to go except place it with the ribbon around it somewhere under the hatch. The safety pin can be difficult to find. Once it went missing for me, and another time for another crew member, and we had to stick our hands deep into that hole in the door.
I won't even go on about 767 and the door itself and the procedure to arm and disarm the slide. It's the same with 737. It feels very outdated having to bend down and move the girt bar.
If I could design a door, I would place the door selection handle either at the top of the door, as on 777, or at least at the middle of the door, as on A320. Bending down as you need to do on 747 is awful even though it only takes a few second to select the door mode.
