Okay, im not too sure if this or where this has been brought up before. but might i suggest a possible stacking option for all items NOT being used. Like have all the items of the same name & everything stack. where a number of the stacked amount will be displayed to the side. And when the new trade is implemented it should make it alot easier to navigate through the items. and have the option of offering (x) amount of an item when trading. Might also help with the showing off screenshots also.

Tell me what u guys think? or better this idea?
