Suggestion

Making JEI plugins be able to be created via a datapack could be interesting and beneficial towards datapack creators in several ways. For one, recipes added via datapacks could be displayed with custom names, rather than by their namespace. Secondly, custom crafting categories could be created, which would be beneficial for making unmodded custom crafters and methods of creating items. And finally, items with custom NBT could be added to the JEI menu for ease of access.
