Please add new stair types like spiral stairs, elevators etc.

As a builder it would really make it easier to build and imagine new builds if you had a plethora of stairs. The connection between two floors has always been that single stair type that takes up to 8 tiles.

There are just so many different stair types that would expand the game to a whole new level (pun intended).
- switchback stairs - stairs that folds back in the middle taking 4 tiles
- ladder stairs (1 tile) for treehouse
- elevator of course (ranging from 1 tile elevator to 4 tiles)
- round stairs that occupies a square of 4 to 8 tiles depending on the grandeur :-P
- spiral stairs that takes a 4x4 or the really tight spiral stair of 1 tile
- tube stairs (future elevator that sucks you to the next floor) 2x2 tile or just 1 tile
- pole stair like the ones at the firestation
- rock stairs for the neaderthal build
- - no stair type - where the sim just teleport from location to another location. 1 tile - start and end teleportation or a chain of locations and the sim chooses the end point if you place a series of them down.

After 16 years of sims, isn't it time to add this to the base game. Spiral stairs as a start for castles would be nice.

Thank you for reading.
