-improve or allow for building an enhanced orphanage, nicer amenities or improve the one present. Those you cannot adopt can be directed to these nicer location(s).
-regardless of which side you choose, assist and overhaul the grey quarter out of pocket if you have to. I'd honestly love to provide them nicer homes than their racist community members.
-establish argonian and khajiit settlements where they are self sustaining and have actual homes, migrating away from slave labor locals and/or solely khajiiti caravans. Those needed only return for work hours for gameplay purposes.
-allow for not just a single septim but warmer clothing to be given to beggars or allow them to stay in your purchases houses.
-overtake bandit locations (I'm experimenting with a single mod that toys with this), but it would be nice if it be further expanded as locations of working class self-sufficiency.
You end up all powerful with a disgusting amount of gold, its sad there isn't more routes to being a more positive force for change.
