Usually it would be a bad idea to open the door when you hear bunch of people hacking it down with axes, but in this game it's a common tactic. If the door opens inwards, you can open and close it real quick so that people can't hit it, and they don't have time to get in either. Or if it opens outwards, you can (ab)use it to push people off stairs or a cliff.
So, would it be possible to add door kicking / nudging to counter this tactic? Meaning that when someone is trying to open or close the door, you could kick or nudge it to opposite direction to keep it the way it was.
