The mod currently adds several decorative books. The player should be able to apply these books to the enchanting table, which will either change the design of the table, or just the book rendered on top.

The first option of changing the entire design would be cool, however it would require new models and textures be made for all the variations. The books can also be recolored, and if I want to keep that feature applicable to the E+ table, I would have a harder time changing the color of the JSON model.

The second option of just changing the book texture can work, but would feel slightly incomplete.

If anyone can help contribute textures for the variations, so we could do the first approach, that would be really appreciated. You can find the current book textures here

if you manage to get multiple model for the table, maybe use the floating book in the Table Recipe instead of Writing Book?

I would like to add onto @drakray's suggestion, maybe combine the enchanting table and the book in an anvil. Or have a slot in the GUI of the enchanting table. So that it can apply the texture, and can be removed whenever.
