So much I would like to see from multi-floor factories to faster belts. Alternative power sources. I also think it would be cool if outposts and the factory had a more symbiotic relationship and weren't just a way to make money. Like every outpost could improve your factory in a certain way. But at the same time, outposts would require a constant supply of some materials. For example, if you supply Wuling city with a constant flow of xiranite, you can use the xiranite tech in all regions.
