Can we set it so that House Stairs can be hidden, possibly even have them have tiles adjacent to them < at the house owners discretion > also lead up there? Sometimes you want 2 sets of stairs leading up to the same area, but just can't manage it or something. It's more or a mapping thing and thematic.

Invisible stairs for use with doors? Hell yes.

Not even really using them with doors, but more like stairs that continue on up without ending < See: Giant staircase that leads to 2nd floor >. It just would make making mansions/trapdoors/pitfalls so much cooLER

...Just the ability to have the Extra Level item be a blank transparent tile
would be wonderful, so you could throw one at the top of a staircase of
DISCer floor tiles without breaking your design aesthetic. Coupled with
this would be the ability to have the same Extra Level item cover a 3x3
area of tiles, so that you could have 3 tile wide staircases that actually
change floors. Each one would lead to the same Extra Level, so you can't
just buy one and get 9 floors out of it. Purely cosmetic for more creative
house styles.

I think you can already put doors on top of Extra Levels, then lock the door, and when you collide with the door it would work as if you had hit the Extra Level. May also work for walls, but have not tested.

Also: the door thing also works for the Exit mat thing.
