I've harbored a thought which, incidentally, might also be more reliably testable for QA. Rather than rely upon drag-and-drop for reordering queue entries, provide explicit move-up and move-down performing small buttons, one pair per visible queue entry. Of course, drag-and-drop might be considered visually cleaner (no visual affordances) and allow for move-by-several-slots larger motions. Would that the current YT UI actually allow drag-and-drop-between to work as expected.
