Little QoL type additions you'd like to see added?

I'd love to be able to see a girl's skill level in her portrait, especially in the Skill Training menu. I can rarely remember how high a girl's skill is and needing to click them all to see who I need to work on takes a while. Being able to sort by skill level would be great too. I'd also like a way to unequip all girls in your inventory at once. Sometimes I just want to redo all the items to make sure my best girls have the best items. I forget items on girls I don't use anymore too often...

Maybe there's a way to do these things that I'm not aware of? They seem pretty easy to do and would make things a lot easier/quicker.
