This Factorio mod allows you to route belts/pipes automatically using A-star/Dijkstra algorithms. (Algorithms will be eventually migrated to MiscLib repo)
Firstly, thanks for the awesome mode. My factories would lack so many spaghetti qualities without your work!
Secondly, Some of beltrouters designs are just too cluttery, and very cumbersome to remove. It'd be great to have either an undo, or an option that a path needs to be accepted before it is converted to ghosts. That way I could try, see whether it's ok, or whether I better make some space.
Mod trys to mix vanilla and modded pipes when I try it, also is there anything stopping you from just supporting all normal (1x1 sized, normally connecting moddes pipes?) just get the max underground distance from the pipes and use whatever type of pipe was selected.
