There are a lot of mons who, upon evolving, wants to learn like 15 moves all at once. And it becomes increasingly tedious when you have to manually skip each of them. It also happens when you feed a mon a decent amount of exp candies and after that, the mon levels up and wants to learn tons of different moves and you gotta go through every one of them again.
Anything that makes this process more time effective would do. Personally, I would love that you are given a list of all the moves that your mon wants to learn at that moment, you can either skip all of them with just a click or choose one or two of them.
