Just cleaning the rented properties would be great. The carpenter kit could be used by players to customize as they see fit. Add beds and big tables and voila !
As for other customisations options... how hard would it be to implement more minor feats or backgrounds ? I was thinking we could implement some sort of "flaw" feat.
Like say:
Allergic: minus 2 to rolls against poison.
Phobia : reversed favored enemy pretty much
Coward: minus 2 save vs fear and terror
Etc.
