There are countless buildings I have lost to time. So, how could we keep them? Let me introduce blueprints.
Blueprints would be a menu tool that would map out block/paint setups to your menu. They would be captured into the menu, and they would be created with 1 Blue dye and 2 wood. You could place them to create a transparent model for your building, and you would place in from there. If you clicked on the blueprint, it would show you all materials needed (including paint combinations.)
Apologies if the formatting is a bit off, I just want to keep my buildings.
