    Marks Youtube videos as watched in a playlist. I am going thru a video series that has a video a day and it was getting hard to track what I had watched. The videos you have watched show greyed out and WATCHED is displayed. Exactly what I needed.

    extremely straightforward and honest extension thats good at what it does. its great at integrating already watched videos from the browser history, and has simple but well designed customization for how a watched video is shown in the feed. although i do wish that it could have an option for cloud backups so it could be easier to integrate for multiple devices and browsers at the same time, but i understand that this could be stretching the project further than it can especially for a passio...

    Amazing extension, but youtube just broke it again. Really sick of them ruining the site, least it looks like you've already got a fix being pushed out according to the github. Thanks!
