Bookcase

The Bookcase can be made from any of the 6 different vanilla woods and will look like the wood that is used.

Player can place books directly in the Bookcase by right clicking with an accepted book. Right clicking the Bookcase without an accepted book OR if the Bookcase is full will open the GUI. Sneak clicking with an empty hand will pull a book off the Bookcase. Books will add/subtract from the slot the player is aiming at.

Works with enchantment tables! The books are counted and 8 books count as 1 vanila bookshelf. So a full bookcase counts as 2 vanilla bookshelves.

Recipe
The bookcase is crafted using planks and wooden slabs
