It would be nice if you could see item quantities (and stats, for that matter, but I'll just take quantities) when you hover over the icons. This would be similar to how it works on your profile page when you hover over the item name in your inventory. It's pretty labor intensive to locate an item, and then try to figure out how many of that item you have. I have almost 700,000 items in my inventory. This would be a more dynamic set up than what we have now, which means it's probably not even going to be considered, much less approved, even much less implemented.
