Any chance to get a per surface network? AFAIK, currently there is a single network, which makes cross-planet/surface transport trivial. It would be nice to still have the challenge of using rockets/ships for inter-planet transport. This could also be a config option.
A full rewrite for per-surface networks would be a major change and a lot of work. Since the mod is stable and feature-complete, I’m not planning to make any further updates unless a future Factorio update breaks something.
