It would be nice to see how many different pet families use a specific attack.
For example, suppose you liked "Frog Kiss" but you were hoping it might have been paired up with other attacks than the ones Biletoad has.
It would be convenient to be able to discover that only one pet group (of 17 pets) use that attack.
However "Ion Cannon" has 2 pet groups that use it, Tranquil Mechanical Yeti or Darkmoon Tonk.
This would help us find that mythical pet that can stack buffs and deliver 2000 damage in one blow, or one that can simultaneously damage well and heal well, or whatever strategy you think would be neat.
