Build Mode Feedback for EA

Terrain tool my top want. I want to build and style my own lakes, hopefully basements become a thing where we don't have to place stairs into the ground.
Hexagonal roofs, etc yes.
Garages with operational garage doors. expected in a cars stuff pack.
assuming in time we'll be able to exceed 3 floors.
foundations, hopefully we can build on different levels or no foundation like if i wanted to build a shed out in back of my house.
wall heights I love it, but sometimes I would like my living room walls higher than my kitchen walls in the next room.

more of a game play feature locking doors. i felt that should have been a thing.
