This is just a tiny thing, but I would appreciate it nonetheless.

You know how if one of your lionesses hunts an animal you need for a quest it notifies you and links you to the Snake? I'd really like to have something like that for leveling up. When a lioness gains enough exp to level up, I think it would be cool if it notified you with something along the lines of "You have a lioness that can level up! Go to your den to see!" or something like that with a link to your den.

It's not a major thing, but I like to keep my girls leveled up and sometimes forget to check after a few hunts.
