I noticed the "Find Fish" tracking is not an option in the Spells.

Can this be added?

Also - it'd be cool if it was automatic like when Paladins with Crusader Aura mount but instead of mounting it'd trigger when you equip a fishing pole.

Find fish was added a couple weeks ago.
But it does not respect a fishing pole in your hand. If you have multiple tracking enabled in Buffomat, it'll keep whatever tracking you activated last.
