Maybe you could incorporate a way to request a certain amount of lanes for the ore output? Like, if early game with big patches, if you requested two lanes of yellow belt, but the patch planner could only set up two lanes instead of covering the entire patch.
I know it's pedantic, and easy to just put down 60 miners, but for asymmetrical ore patches, it'd be nice to have a layout already planned with enough rows to balance out a certain amount of lanes.
Just an idea! Thanks for the mod as it is, it's pretty awesome!
