There was an addon for Vanilla WoW that made Hunter pet management so much easier and convenient - it was called "SmartPet". It would basically manage the focus of your pet to always have enough focus for important abilities (e. g. Growl), would automatically disable Taunt in dungeons/PvP and would make your pet not chase fleeing targets.

Would it be possible to port something like this to the upcoming Classic WoW?
