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.

Very nice extension. I love it. I'd love it even more if it would be possible to choose another value (rgba) for the overlay color. Maybe you find some time to implement it. That would be really great.
I have tried several of these types of extensions. This is the only one I tried that actually works.
I tried so many different addons that was supposed to mark videos as watched but this one is the only one that actually works. Thanks a lot man!
Great extension! It fixes Youtube's defective watched history. I used to use the Firefox version and i'm glad i found it for Chrome (Vivaldi).
Best ever. Does exactly what it says and has customizability
Other chrome extensions don't work for me but this one does!!!!! Rated as ★x99999999999999999999
