#1) Don't really see what advantage this would have over the Item Comparison as we have it now.

#2) This would be really nice. I'd still like to see which of those stats are coming from the materia, though, and which from the gear itself. So instead of just "Spellspeed +65" and "Skillspeed +9" in italics, I'd rather see it as "Spellspeed +65 (53 + 12)" and "Skillspeed +9 (0 + 9)". (That and/or keep the stat adjustments listed in the materia section as well, like they are now, but then also have the Bonuses section include the total.)

#3) Yes, I've been wishing for this, too. I was glad when they added it for the top-line damage and defense fields, but really want it for all of them.
