I have noticed that you can move an item or group of items up in the queue by selecting items and clicking on the up or down arrow beside the word Queue. It would also be very useful to be able to move one or more items to the top or the bottom of the queue.

Another annoyance in the download pane is the info popup that gets in the way when the mouse moves anywhere close to an item in the pane. I wish that ther was an option to disable the popups in both the search and download pane.
