Script Summary: Show video ratings on Youtube, based on "Youtube: Show Ratings" script
Stay away from the weird part of youtube
Show video ratings on all Youtube videos. Hover a thumbnail to see the rating bar and details.
This is a slightly modified version of Youtube: Show Ratings by Nikola Kocić. Adds one bug fix, and instead of displaying all the ratings and always - shows only one at a time when pointing the video with your cursor.
