Is your feature request related to a problem? Please describe.
I would like to be able to only hide the enchantments of an item since hide-flags hides ALL of the attributes, such as firework color, and damage the item does.

There could also be flags for other specific attributes as well.

Describe the solution you'd like
hide-enchantments - Hides only enchantments.

Describe alternatives you've considered
I've just been using hide-flags and could input the lore myself, but I feel like it would be much simpler to just hide the enchantments with a flag.

Seems simple enough, will update you here once I implement it.

Apologies that it took so long to get to this feature.
Good news though! It has officially been added in the latest snapshot and is slated for the official release!

Remember to remove your old ItemJoin.jar file

Simply specify the itemflag hide-enchants and enchantments will be hidden on an item.

Let me know!~
