Save & load premade housing setups
It would be nice if you could save/load housing interior setups but in 2 parts per floor.
So when you enter a mansion for example, you could save the left side of the floor and right side of the floor separately and load a saved setup for each side while doing this for each floor separately. This system would apply in all houses whether it's a small, medium or large house... The left and right side of each floor would be stored separately and you would be able to give each plan a name.
It would make it easy to test various things and perfect the best combo's without having to redo it every single time you move your house to another location.
