One request I have is add a simple villager AI : Villager try to go inside nearby door when rain,thunder,storm.

A good idea yeah, same for if a tornado is coming so they dont get grabbed.

Maybe if there is building that is mostly wood and mostly stone. It should go to stone if the villager is able to get there.

Hello, @Potsukin.

This suggestion has been implemented into the game now,
you can now close the case.
