If you saw his post on page 1 you would have seen his so far great ideas on how to improve the mod.
Make jobs unlike regular cityrp, certain actions should not be only applicable to some special job (woodcutter, thief, etc)
Make it so you have to be in a certain area to do actions, school, job, or whatever.
Jail should be a big deal, going with the system M mentioned should work pretty well.
Possibly also have it so you can get others to work for you, you put them on your payroll and they must be within the property their job is at for them to get paid per tick or something and them being there could process metals per tick (in the case of a factory)
That's just a rough idea, and like M mentioned the players would have their own CVs (not custom made/player altered) which shows their history, for example where they worked before, if they were fired/quit, what skills/education they've got, etc.
