When a file successfully completes a transfer (background transfer) it is removed/disappears from the queue list.
It would be nice if completed transfers left some kind of information in the queue list so you could see how long it took. The font color could be a lighter color (grey?) instead of black just to distinguish it from current transfers and waiting transfers.
It would also be nice if failed transfers left some kind of information in queue list as well. The font color could be red and italicized to distinguish it from current transfers and waiting transfers.
