Simply display the full stats of all item of the Trade Window, both topside and bottom. Instead of requiring the cursor to float over the item to show its stats, the new interface could just fully display all item stats in their own adjacent pop-up windows, with lines being auto-drawn from the item icons to their corresponding stat windows if needed.
Yes, it would cause more individual screen clutter, but such a new feature could also be toggled on/off depending on user preferences. Frankly, I'd never turn it off if it should ever be implemented.

PS: I've never been scammed, but I could see this feature helping newer naive players spot potential fraud more easily. Such a feature can only help, not hinder. It won't stop all scams, but any reduction in fraudulent activity is a good thing
