Netflix has made it possible for you to change the position of your movies in your queue just by dragging and dropping them. You have to put your pointer over the movie until it turns into a little grippy-hand. Then you can click and drag the movie to a new queue position. Or you can still sort them by changing the movie's number and clicking the "update your queue" button.
I'm glad that the Netflix Web site announced this new feature, instead of waiting for us to figure it out.
