Floor Height Adjustment Feature

[Quantum]

I need more functionality to adjust the height of floors that are created automatically when a room is formed by building walls.
When building a flat, thick roof or a terrace without walls or railings, the floor becomes too thin, making it look unrealistic.

This is possible when you click on the ‘Room Selection Tool’.

With one of the arrows that appears (marked in the pic below) you can raise/lower the floor and you can even place platforms with different heights next to each other.
