I wish we could have a little 'pop-up' sign on the Mayors house so that when friends visit they could see a 'message' if they click.
Mine would say 'Please buff farm stuff and metal production - Thanks:-)'. or it might say 'Have marble, will do preferential trades'
That would save me trying to remember what to buff where, and would also let friends know what I have surplus of, or what I need.
