Overview
Product summary
Review the store description, core capabilities, and common use cases.
Youtube keeps track of your watch history and automatically marks videos that you have already watched. They however only mark recently seen videos, which is kind of disappointing. This addon fixes this issue and keeps track of your entire watch history, such that not only the recently seen videos are being marked.
***How can the persistence of the database be ensured?*** There is an export and import feature, which makes it easy to create a backup of the history. This backup can easily be archived such that you can ensure that you never lose your history.
***How can I make sure that the database is complete?*** The automatic synchronization only considers the recent activity. You are thus encouraged to manually initiate a complete synchronization in the settings, which incorporates as much of your history as possible.
***Something is broken, I demand a fix!*** Please be considerate when leaving a review, this is a free extension that I invest my spare time in. If there is something that does not work then please file an issue on Github where it is easier for me to track.

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.
helpful 5 * shows visual indicator of videos we've seen, greyscale * no known bugs,
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 passion project by a solo developer, so still 5 stars for me.
Danke funktioniert :)
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!
I wish there was syncing
Good
The best app!
This is a must, thank you. Could you also add a way to automatically sync the history between two computers, maybe using Google Drive or something similar?
Very nice.
