Sorry, hope this is the right forum!
I'm not sure if this feature is already there actually, but I've been searching and not finding it so I'm gonna try and suggest it:
I think it would be super neat if we could "lock" a pokémon. A locked pokemon can't be moved nor released (you'd need to unlock it to do so).
It would be handy when you have many pokemon and you want them to stay in a box but you get confused and they end up in your active pokémon and then released. Thought about that when I found out I accidentally moved a pokémon out a box and almost released it. ;w; It's very difficult sometimes to pay attention and accidents might happen... a lock feature would definitely be helpful, I think.
