Hatches and Barn doors?

[Uhlan]

A couple of very useful additions to Epoch, I submit, would be hatches (doors in floors) and doors with no top frames (barn doors) so vehicles like MTVRs can fit through.

 

Hatches could be in 3 general sizes; 1/4 floor, 1/2 floor, and whole floor.

Barn doors would basically be split, side opening garage doors in a large wall with no top frame so the space above could be left open or another door stacked on top to make a very tall door, or even a regular garage door above the barn doors.  The doors could swing out, hinged at the sides, or slide to either side like a true barn door.  All of this being lockable as per the current door selection.

 

Stair railings would be a very handy addition, possible replacing supports?  Why are there stair supports anyway except for aesthetic purposes?
