Watchmarker for Youtube

Automatically mark videos on Youtube that you have already watched.
What is Watchmarker for Youtube?
Watchmarker for Youtube is a Chrome extension intended to enhance your Youtube experience by automatically tracking and marking all videos you have watched, unlike Youtube which only marks recent videos. It ensures data persistence through an imprt/export feature for easy backup. However, complete synchronization needs to be initiated manually. Developed as a free tool, it is open to improvements through the Github platform. Note: Currently, it only supports the new Youtube theme.

Extension summary

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.

Does this work with the old Youtube theme? I am afraid that only the new theme is supported. If you do not know which theme you are currently using then it is very likely the new one.

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.

Sometime early September, shorts no longer have the WATCHED tag or the greying of the thumbnail. really annoying. A channel shorts page I still had open still has the WATCHED tags with dates and greyed thumbnails. I watched a short I did not before and it was updated in this old browser tab but not a fresh one.

Me gusta porque sí te marca los vídeos que ya viste. Pero mi única queja es que antes también te marcaba como visto los shorts pero ahora ya no, así que ojalá pudieran solucionar eso y hacer que de nuevo también los shorts sean marcados con el visto.
