I've been modding the game as of late, and I really want to make structures with some sort of entrance for the workers to go into. Seeing as there is no specified location for them to go into, I think right-clicking a block and selecting "make a door block" should be implemented. This will change the block into a "door" for the colonists. Meaning they will pathfind to this block to enter the building, and the block will be able to be traveled through via rovers and workers.
Fun fact: I modded the game before I even played it.
