Netflix "Shuffle Queue" button
I've been a loyal Netflix customer for years, and one feature I'd love to see is a "shuffle your queue" feature. I've emailed them this suggestion many times.
I get on kicks sometimes while adding movies to my queue, so there's blocks of war movies followed by blocks of trippy movies...etc. Moving them around is easy enough, but often I wish there was just a simple button that would shuffle the queue into a random order.
