Book Reader
The player looking at a book on a chiseled bookshelf, with 'Unbreaking III' in the actionbar
If an enchanted book has multiple enchantments, it shows them all in a list like here! (Feather Falling II, Smite III, Unbreaking I, Fortune III)
As of version 1.1.0, the book reader now shows the list of enchantments in the viewer's language! (Fléau des arthropodes I, Malédiction du lien éternel I)
Players with different language settings looking at the same book will all see it in their language! (Bane of Arthropods I, Curse of Binding I)
The book reader only reads the book when you're actually looking at it, so you won't see random messages if you're just looking at the side
The book reader doesn't get triggered if you look at any other part of the bookshelf
