Make the command book enchant, similar to other enchanted books.
(Sorry if I have bad grammar, I’m not good speaking English)

What would the enchantment be? Regardless that isn’t the purpose of the books and I don’t plan on making them enchantments.

I think that they meant for the book to be applied using the anvil instead of the smithing table.

Ah that makes more sense. Regardless I’ve outlined my opinion on the idea here anyway: #362
