One thing for me that made building construction tedious was the fact that I have to walk next to the tile where I do my constructing. On stuff like making a long wall, this made it tedious since I also have to lug around the materials needed.
So, I got a suggestion. How about there’s some sort of advanced construction menu? Something like the vehicle construction thing, where if you do that, you get a screen much like the vehicle construction, and you only need to stand on one spot as you start constructing walls/furniture/whatever in an area with the benefit of staying in one place and only needing to set down your materials close by in one pile. Something like that.
