Have quick glance at likes and dislikes of Youtube videos.
It is very simple application just does nothing else than showing number of likes and dislikes of a video instantly on placing your mouse on any video in YouTube page.
It was developed for my use as I have been wasting time watching spam and unrelated videos. And the problem is we cannot identify how many likes and dislikes does a video have until and unless we click and open a video.
But with this extension you just place your mouse on any Video and it will show how many likes and dislikes does a video have instantly in same page. If you have that info with you, you can decide whether to watch or ignore the video.
