Yeah I have found it quite annoying trying to find where the move tutors for certain moves are. At least TM moves tell me the TM number, move tutor moves only tell you that they are move tutor moves.
On a completely different topic, do you think a category for "moves that can hit semi-invulnerable Pokémon" would be useful? But the main question is, should it be divided into "moves that can hit Pokémon that are up high" and "moves that can hit digging Pokémon" etc.?
