I've played another game where as you gain skills it allows you to wear titles. I think this would be a good addition to LiF as it allows people to assume roles within a village and not have to keep a log of who's job is who's or what job that person is doing.
Even with our small village of 10, knowing who is doing what job makes things much easier.
EG: [Logger]Len Harvey or [Herbalist]Dan Simco etc...
