It would be nice if this mod could also be used to automatically place agricultural towers in the spots with optimal resource generation (most usable squares) given a certain level of technology (nothing/artificial soil/overgrowth soil).
Limiting placement of multiple towers to square grids would be totally fine (due to both complexity and (potentially O(exp(n))) runtime constraints for the general case); trying to place power poles on (currently) unusable terrain instead of at a fixed offset to the tower would be a plus.
Placing seed/output belt blueprints would also be nice (optimizing underground position seems easy, since you only have to keep track of at most min(underground_length,tower spacing) different "costs" when planning a belt pair ((basically slightly optimized Dijkstra over possible underground connections)) ).
