I was currently training someone elses pokemon, when I found I couldn't change the pokemons moves to suit the training. I wanted to give the pokemon back so the trainer could change the moves, but it didn't allow me to as it was loaned. So there should be an option to return the pokemon even before time has expired and also make it that you can change their move sets but when the pokemon goes back it gets its original moves back. Would make the game simpler
