Ability cooldowns don't reset when you leave the dungeon.

Offering a freed slave to join causes a blank window after selecting character, in which you can click an invisible button that brings you back to the character select screen.
Need a remember party, or a keep party together option.

Praising or warning slaves every day is tedious, not fun. Adding some passive daily increases for social/sex classes would be better than having to do it by hand.

A way to elevate slaves to servants would be nice.

Free multi-target spells are way too strong, you don't need anything else most fights.

Highlighting which job a slave is best at would save time.

I agree having to use abilities every few hours to top off a Slaves obedience and fear is very tedious and often than not I find myself having to do it constantly.  I've chosen the Head Girl Class assuming it'd allow that character to manage a few Slaves for me but that doesn't seem to be the case. Maybe consider doing it like that?

Yeah, items, slaves/managers and policies that do that automatically would be needed.
