Dyeable Enchanting Tables, Different wooden bookshelves

My idea starts of with the fact that enchanting tables are now made with a wool instead of obsidian between the diamonds, and the enchanting tables' carpet being the color of the wool used, or perhaps dyable if the wool used is white. The idea for the bookshelves is that there is too little variety between bookshelves, and that the main texture hasn't been changed for quite a while. That would generally make it so that instead of using any plank for the bookshelf, you need all of a specific type of wood where any plank used to be. That would change the bookshelf wooden part to look different and change the current bookshelf to become an oak bookshelf. Crimson, dark oak, even birch bookshelves. Change one of the few remaining only oak items that remain in the game.
