My first Minecraft server plugin adds small QOL functionality to Tridents [+fixes offhand looting]. Originally made to let players use Loyalty Tridents to grab out of reach items, decided to push the idea a bit further.

Commands/Features
Dropped Items attach to Tridents on collision
/toggleGroundPickup

Mobs will attach their drops to Trident it is killed by
/toggleDropPickup

Tridents can impale other players
/toggleCanImpale

Holding an EnderPearl in your offhand will attach it to the Thrown Trident
/toggleCanPearl

Holding a Lead while you throw a trident will cancel its damage and attach the Entity it hits.
/toggleCanLead

Tridents will return to the slot they were thrown from
/toggleTridentHome

Holding Looting in your Offhand works again!
/toggleLootSim

Never had to use during testing, but just in case TridentHome gets stuck
/clearTridentHome
