I would love better playlist controls for Youtube. I do a lot of playlist shaping and even their web interface is broken -- for instance, if you have a playlist with 100 items on it and you drag-n-drop to re-order, the visual order doesn't match the saved playlist order. I then re-load the playlist and have to scroll back down. I'd also like to shuffle certain playlists, not in playback, but the way it's stored.
