You could also pick the spell gem window you like the most, make it a little longer and stick your own, or a copied, little spell book icon in at the bottom. That way you'd get just what you want.
I posted a full UI in the mix & match area a while ago that had all the things you're asking for... I didn't split each of the pieces and post them individually, however. I think I called it nwinnUI and it'd be back a ways if you felt like looking for it.
