It would be great if we had flags to check in the spell editor for each of the schools of magic, then we could play (2e) illustionists, necromancers, evokers, etc.
Plus, you'd be able to take care of the 1e Illusionists, too.
The downloads there aren't that useful for 1e, it's true.
But, they are a good starter for anyone interested in 2e.
