Hi. I remember playing with another mining planner back before 2.0, I believe it was called Outpost Planner, that after placing the miners it'd also place ghosts of the belts routing to be one next to the other. Just making all the belts next to each other so that one would be able to just paste a balancer or warehouse/merged chest at the end without having to route all the belts first every time. Is it possible to add the functionality to this mod?

Here is a video showing it

This mod basically needs a rewrite and a unit testing solution before I'll add any new features. I was actually experimenting with a dedicated belt planner before Space Age but I don't have an ETA for that.
