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.

I love this extension. One feature I wish it had is a way to select multiple videos for deletion. Like using checkboxes. And also a way to retain your search results, so that when you delete a video, the search results are not reset. Other than that, near PERFECT extension.
It's finally back! Thanks for fixing it, dev.
Absol-f'ing-lutely amazing app. Can't imagine going back to watching YouTube without it!
Five stars for when it works... please update!! Not greying out watched or timestamping watch date... not really working at all. edit: updated and working again -- thank you!
not being marked as watched.
Has not worked for about a week. Please update!
Update this so it actually works again.
Please can you restore? Chrome suddenly disabled it and don't know if I lost all my history...
Please, please, please, can you update this for mv3
