i see we have add spell book entry is it supposed to add a new book to the hot bars or does that need to be coded
into that lua spell

You might want to check out the SendNewSpells(int8 class_id) method on Client.

i should have been more clear

AddSpellBookEntry Lua function , it does not currently but i added the functionality so it will
i am also going to add an option to the lua function to specify whether or not it should be added to the hot bar,

in the coded most places that use the AddSpellBookEntry non Lua function have a remove spell bokk entry for previous versions ie removes adept if you are adding the expert and the sendpellupdate function allong with it
which adds to the knowledge book and gives you the update message on screen
