Some suggestions I've thought of my first week playing:
When placing new buildings I often accidentally place them with the "entrance" facing away from the rest of my civilization, so nuggets have to walk the long way around to get to it (e.g. workers entering the farm). I know you can turn buildings with Q and E but they rotate very slowly. Maybe add something so that holding Q or E rotates it how it is now, while pressing Shift +Q/E turns the building 90 degrees so we don't have to wait as long to place the building how we'd like it.
The game keeps track of spouses and children already, so I think a family tree diagram would be cool to look at!
