When you disable Bagnon (gasp!) and you go to the vendor it displays coins in the upper left of the icon of the gray items or items that are safe to sell (I think). Wonder if you could do the same thing when you go the vendor and sell it would put the coin icon on the item. It just makes it easier to find the junk in the bag that needs sold.

+1 for this. Is there any chance to see it implemented soon?

love this idea more than the highlighting in grey. i still have to mouse over everything to see what is vendor fodder and what is not.
