Working on a update

New navigation.

A updated navigation is on the way. It makes it easier to select which spellbook is active and the spellbook-page is getting a new look to make it easier to view from smaller devices.

I'm rewriting the spell-page to be able to expand more information about the spell without the need to open it up in another tab. You should also be able to add a spell to the active spellbook without the need of a page-reload.
