About the showcased new library block

Only 6 books are very too little, when chests can literally have 27 of them in the same space occupied. Not to talk about the incongruity between the width of books from the usual bookshelves. One should be able to put at least 10 books in them. Instead of the last-in-first-out-thing, which might be very annoying, especially if the new block could (and really should) hold more books, the new library blocks should really work like chests, with an UI, but, unlike them, the cover of the books should be different basing on the enchantment or on whether it's a finished/unfinished book and quill when looking at the block: every enchantment should have its cover color and a small tag of other different colors basing on the enchantment level: this would make the new block waaay preferable than the chest, for storing books and would make it possible to create various combinations of bookshelf colors, for costum maps with libraries. TLDR: Different books seen different when looking at new bookself; more books in new bookshelf; chest UI for new bookshelf
