Better, but still more trouble than its worth.Sorry I didn't mean to imply the keywords would be A B C etc... I was just feeling unimaginative.
I'm speaking like Fireball [Fire] [Damage] [Area] [Ranged] [Evocation]
Or Knock [Manipulation] [Thievery] [Exploration]
Or some better idea than that... But you might give a class access to all [Area] spells or All [Thievery] spells, and not have to worry about making a list that is outdated by the time it's published.
flame strike [area] [holy] [fire]
should the wizard have access to this one? I guess not. So in the end, you are back at some lists.
Wizard has [area] spells, but not those that are [holy].
In the end, new books can list them as [cleric] or [wizard] or if all arcane casters can access them: [arcane], [divine]...
