It might just be me who has this issue, but I have a cave labelled 1[main cave], because I would like the lions in it to show up first when I'm feeding or using toys from the hoard, but it has never worked. I've tried renaming it, renaming my other caves, moving the lions around, and even if one of those worked, unsorted would show up first!

It annoyed me so much that I now have a cave just called "STOP" because that's the only way to get my main cave to show up first on the list.

I propose that from the "View Pride Overview" tab on your den, you should be able to drag caves up and down in a sort of tier of importance system, so that the cave you have up top would show up first in the hoard and other tabs. This would help streamline feeding/playing to those of us who have a lot of lions, and just make it less frustrating to transport lions back and forth.
