The following commands can be added to add kits-
1./kit create- creates a kit with the player's current inventory (only for admins)
2./kits - shows list of kits in the chat
3./kit claim - gives the items of the corresponding kit to the player

Several people have requested such a feature. I might create a standalone mod for this when I have time.

That would be even better 👍

Base functionality of creating, removing, & claiming kits (with suggestions), per-kit permissions, and kit cooldowns currently implemented in v1.1.0.
