Drag and drop re order downloads

On the main download screen when there are several download queued up and waiting it would be nice to be able to drag a lower download to a higher position. Right now I don't see any way to re order the downloads. The order you start them seems to be the order they must be downloaded. I can pause downloads to allow a lower one to start so I should also be able to just drag it to the order I want it to download at.
