When doing Expert delivery for the Grand Company, you are presented with a linear list sorted by I-level (and some other thing unknown to normal people - probably some hidden item number known only to developers - alphabetical would be better for human players - just sayin'). You MUST click an item to deliver it. You can't just drag and drop from your inventory into the list. AND the list includes each and every item you are carrying that could possibly be delivered, including those that are in your inventory, are part of a gear set, etc.

I have exactly 100 pieces on that list. I've got all DoH and DoL outfitted in top gear - each of those items appears. I have multiple jobs in DL or lower EX gear. All of those items are listed also. It is so frustrating to have to look through all 100 pieces on the list to find the piece from my INVENTORY that I want to turn in, even if I focus in on the I-level.

At least provide an option to limit the list to that which is in your inventory, excluding the Armoury Chest.
