There should be a recipeed tree in crafting. Scrolling through what I can make is a nightmare right now. A tree structure should be made or it should be allowed for players to sort their recippes the way they want.
Homesteads should be allowed to build cities. 20-30 people can make a village in the future, 30-100 a town. With mayor, stores etc. Imagine the implications of that, whole new world of politics and organization.
