Rated 5 out of 5 stars

Excellent!
Awesome!

I use this extension to manage information of my favorites from YouTube.com, which lacks this feature.
If I'm on a page of my favorites and soon after another, I will have the consistency of the names of the videos and my notes.
Although Diigo.com also use for this control, this extension did much better, besides recording the data locally.

This review is for a previous version of the add-on (0.5).
