If I ever have or want to move a building I always have to demolish it, then reconstruct it in the new place, which is annoying. It would be so much easier and simpler if you could just move buildings. Also if you are constructing a bigger building and you need more space then this feature would be very useful.
Maybe you can just move the building by yourself, or maybe you can make villages move the building (somehow). If a villager were to move buildings it can be the ones that work at the worker post or something. Anyway, I just think this would be very handy!
