There are a couple of proposals I have for expanding the current system of Nobles and Positions as well as the customizability (in the raws) thereof:
1. Ability customize noble positions to require rooms other than bedrooms, tombs, dining halls, and offices. Particularly noteworthy types of rooms which currently cannot be required by a position include Sculpture Gardens, Zoos.
2. Expansion of the current [RESPONSIBILITY:...] token system to also be able to designate normal labors which the noble will perform (and cannot be unassigned from while occupying their position) even if otherwise MENIAL_WORK_EXEMPT (the MENIAL_WORK_EXEMPT token would not be implied by these tokens however). For example, the Dungeon Master position might be permanently assigned to the (normal) 'animal training' and 'animal care' labors, in addition to the training specifically of unusual beasts, or the Chief Medical Dwarf might be automatically assigned to one or more medical labors in addition to diagnosis)
3. Corruption. Law making and law enforcement nobles who have grudges against other dwarves, as well as very low levels of DUTIFULNESS, STRAIGHTFORWARDNESS, SELF_DISCIPLINE, or SYMPATHY (or truly abysmally low levels of COOPERATION and/or MODESTY) and/or very high levels of ANGER, (ideally, multiple traits, as well as the dwarf's current mood and their position's level of PRECEDENCE, would be factored in) should occasionally have the dwarf whom their grudge is against arrested on false charges.
4. It would be neat if some of the nobles (which ones would determined by either traits/attributes or perhaps an additional tag in the responsibility token) with the RELIGION responsibility had some kind of minor miraculous healing ability (nothing major, perhaps just an ability to perform the suturing labor without requiring thread or something like that)
