Consummables don't appear in the spellbook and I also use consummables so it's a bit more job than just 1 or 2 spell(s) / level (for every characters).
Anyway I'm not going to argue and quote every sentences to say you're wrong while I'm right
The UI/hotbar management is something I HATE and many games have great systems.
Ofc you're free to like it.
