A few thoughts, some of which have been said before:
It'd be nice to be able to gift clothing to a partner and see them wearing it. If they're a sub, maybe be able to make a rule that they have to wear it (such as collars that say "Owned")
When you become manager at the River Rat, it would be cool if you could create your own uniform. Like maybe you select one of your saved outfits, and the total cost of those clothing items for all your wait staff gets deducted from your budget.
I think it would be interesting to be able to set world generation options separately for the student body. So maybe an all Men or Women's college in an otherwise normal town, or a college that has a higher LGBTQ+ population than the population at large.
