Every time when I am founding item, I have only two options for it - equip it or put away (ok, actually it's 3 - trade, if I have 2 heroes in one place). But why I don't see comparable stats? Ok, I found new weapon, new cloak or new helmet - must I equip it or keep my old one? I don't know.
I see two ways to solve it: either show old item that will be exchanged near "Equip" button, in FF-like style - or open full equipping interface for me to compare manually. Can it be done as menu option?
