And please, assign a different item graphic for each skill book. Don't be lazy and force the player to mouse-over every identical looking skill book just to check what they are.
Senses are pretty common. Everyone can tell one glance that each skill icon is different from one look. But put those Fire books next to each other, and you can't even tell what they are. Wasting more player's time with mouse-overs.
The book icons look a hell of a lot more classy than the ability icons, when sold from the store. I politely request that no such change be made. I can mouse over all the books in under a second.
