My suggestion is exactly what it says in the title!

To elaborate, though, I'd love it if, in the list of adolescent females you can send on a hunt for training experience, it would show what percentage they're at. That way, if I have a lot of girls, I can see right away which ones are already at the minimum 75% for getting a stat boost upon reaching adulthood!

I just sent my girls on a hunt, but when they get back I'll do a little mock-up of what that could potentially look like.

I suppose you could do the same for adolescent males, but I'm more concerned about the females, since they're the ones people are more likely to have a bunch of.
