Just a quick note; I'd like to see the spells and spell schools categorized a little better. More descriptors (a la Arcana Evolved) and breaking some of the existing schools into subschools would add clarity without changing compatibility. Illusion and Conjuration are fine as they are; Enchantment & Evocation could both use a little work; Abjuration, Divination, Necromancy, and Transmutation(!) could really benefit from it. Basically, every spell would belong to a school -and- a subschool (as is already true of Illusion and Conjuration spells).
Possible subschools:
Abjuration: Barrier, Condemnation, Negation, Protection, Ward
Conjuration: Calling, Creation, Healing, Summoning, Teleportation
Divination: Awareness, Lore, Precognition, Psychic, Scrying
Enchantment: Charm, Compulsion, Morale
Evocation: Elemental, Energy, Force
Illusion: Figment, Glamer, Pattern, Phantasm, Shadow
Necromancy: Curse, Death, Flesh, Life, Spirit, Undeath
Transmutation: Alchemical, Enhancement, Manipulation, Transformation
