Show the likes and dislikes bar over every video thumbnail in YouTube so that you can know its rating before watching it.
Throughout all youtube.com, this extension shows a bar of likes and dislikes under every video snapshot, just like the official one. In this way, you can view the rating of the videos before watching the actual video, so that you can avoid garbage and spot amazing ones.
In addition, you can move your mouse to the bottom bar and a tooltip will show up to tell you the likes percentage and the total ratings count. You can also configure it to automatically highlight with a blue box the best videos in every page.
