We need better options for doors and passages. The wooden doors and sliding manways are nice but we need ones that are better suited. I would like smaller doors for manways that act as hinged doors on the floor or cabinets
The old manway should be more complete like a wooden trap door.
Also would be nice to have automatic doors.. .
I have already suggested being able to cover doors with different textures and have these planks move with the door.. .. would be nice for hidden secret doors or doors behind a bookcase.
