Particularly when I'm trying to find something in my bank to sell in order to get enough money for something, it would be really nice not to have to right-click and examine everything to get its value.
Seems to me it would not be very visually cluttering to add a line of text under the name of the item which shows the GE value of the item. IMO quite helpful.
Not really a 'marketable' update I'll admit. Shame that good game design comes 2nd to good money-making schemes.
