Thanks for making this mod.
Came here from the LiquidLime github discussion, but found more in it. Found two things.
One it would be nice to be able to inject the ability to use e.g. LiquidLime from the LiquidLime mod side and not needing to edit each map separately. This is especially relevant for vanilla maps. I wasn't able to add LiquidLime to any vanilla map.
Second I managed to integrate Compost on the NF mod map as an manure alternative only problem. The contents of the spreader is not changing it doesn't empty but changes the ground.
