Imagine a long conveyor, each uploader has a funnel on this conveyor. Once the file has been approved, it falls into the funnel. Each funnel drops files at regular intervals (which can be set by uploader) and to the same sequence as the uploader applied files for moderation. This conveyor is RSS feed from catalog.
If you are planning a weekend or a vacation, just increase the interval or add more files to your queue, and you don’t have to work for this time.
Additionally, you can to “put the file in the top of my queue”
