I think there should be some kind of workbench which can allow players to hide certain parts of their building or house. I’ve never done any pixel art but I think this will benefit those who do pixel art a lot, this will allow them to place work benches and any other things inside their art without destroying its look.
It works by covering the building with a “front wall” (like the back walls we have when we place blocks), corresponding to the blocks used in the build. The workbenches effect can be turned off and the “front wall” it creates can be coloured and replaced with other blocks. The player can see the insides of the building once their inside.
