Hi, @RockinChaos
I really like your plugin, this is amazing.
I used this plugin for creating custom items.

I recently realize if I creating a custom player head (I make this for helmet) and give some attributes like {GENERIC_MAX_HEALTH:5.0} and etc it's automatically set them to "When in Main Hand"
so if I use it as a helmet, I'm not getting any effect.
Can you add some config on items.yml like attributes-slot or anything so I can set it manually?
Thank you before :)

Also its same things with elytra :)
