I realize this may not be helpful to you, ubt unless you bind its actions to the cross hotbar or other hotbar, you really do need the pet bar to play the pet jobs effectively. Manual control is essential to getting the most out of certain abilities, such as Garuda's Contagion and scholar fariy's buffs. If you let your pet just do its own thing all the time, there will be situations where you're putting your party at risk (especially in CM/Pare runs)

It's not so important early on, but you'll need it later.
