Simply choose your next video to be played and let the RT playlist handle it!
This extension creates one global playlist, synchronized across all your tabs.
Add some video to RT playlist simply by clicking Add button next to each video thumbnail and it's going to play automatically right after your currently playing video. Add another, and another video and make your own playlist, while you're still browsing Yyoutube. Add button is available on every thumbnail, anywhere on Youtube.
You can reorder or remove your items and make an immediate impact on your video queue.
I hope, you will enjoy this little extension as much as I do :-)
