I've tried looking through other suggestions but couldn't find what I wanted so please don't hate me if someone has already suggested these but I really couldn't find anything. (might be because it is 2.30AM)

Show decorations on featured lion/ess
Pretty straightforward suggestion. I've seen loads of amazing looking lions/lionesses but their cave view is... boring. We have poses visible surely it wouldn't be difficult to have the decors too.
perhaps be able to change background too. (I know it's supposed to be a cave but still... would be nice)

This could be toggle-able from your profile.

Another suggestion is to be able to mass select from inside caves like you can from unsorted.
Say you want to suddenly change a whole cave around, or you've been breeding and want to move all your cubs into either a nursery/sales cave.

again, sorry if these have already been suggested.
If you disagree please tell me why.
