There are so many things I’d like in build mode 
, especially regarding community lots, but not only.
The dance floor:
reflects the floor below and you can only change the structure, but not the tiles: I would like to be able to color the square tiles, with at least two or 3 alternating colors and be able to make them glow, not just the structure.
Like this one, for example
This alternating tile floor, I would like to be able to color both parts, instead one always stays white.
