Spellbooks in lecterns #962
Description
Describe the feature
Currently, spellbooks do not go into lecterns.
In vanilla Minecraft, both signed and unsigned books can be placed in lecterns. When such a book is present the redstone signal strength ranges from 1 to 15 when a redstone comparator is connected to the lectern. The signal strength is proportional to the page number.
A spellbook when placed in a lectern should behave similarly, with each page showing the spells in the lectern's GUI. For example, a spellbook with 15 pages should output a signal strength equaling the page number that is open in the lectern.
Example use cases would be selecting a destination for a teleportation spell circle, choosing which neighbour to smite or which potion effects to apply.
Additionally, a spell circle should have some interaction with it, much in the same way that item frames do.
