YouTube has just unveiled an experimental new redesign called Project Panda, and it's looking good. You can activate the redesign right here (and if you don't like it, you can disable it from YouTube's Test Tube control panel). Some initial impressions: The new design makes significant changes to the way playlists are presented, moving them in some cases from a sidebar to a scrolling horizontal bar of thumbnails just beneath the video you're watching (it reminds me a little of YouTube's LeanBack).
