One of my favorite add-ons on YouTube. I watch 100s of videos weekly and this helps me out a lot in tracking what I've seen and what I haven't. really fantastic add-on!!

Great app. Easy and smooth to use.

Suggestion : Would love an option to change the date stamp format to dd / mm / yyyy. The default one is kind of backwards...

:)

Very useful tool !
Thank you

Works even on different computers. You only have to log in to your gmail and you see all the marks videos you´ve watched on another computer

extremely useful and works perfectly. the only thing i miss is an easy way to regulate how much the thumbnails of watched videos get dimmed. otherwise an A+ extension that i hope lives forever.

Love the add-on, but I recommend few QOL changes after testing it for a day or two, to avoid annoying new users:


1) By default, only these Conditions should be enabled:

- Mark a video as watched once it appears in the browser's history.
- Mark a video as watched once it has the official Youtube watched badge.
- Mark a video as watched once it appears in Youtube's watch history.

1) By default, only this Visualization should be enabled:

- Mark watched videos by slightly fading the thumbnail out.
- Show a textual badge in addition to graying out watched videos.

I recommend this because I was REALLY annoyed that just opening a video by default marked is at "Watched". I'd rather the video actually watched, is labeled watched, because opening a video to watch it later in a tab marks it as "watched" (maybe add option to delay "Watch" status after a video is opened?).

So that means, with default visualizations options on, suddenly all videos I opened in a tab and didn't watch instantly, show up with grayscale, no YouTube bar, "WATCHED" label on the channel. So now I have no idea which video I actually watched (YouTube bar is a must ON to track this) because every thumbnails is generic looking grayscale. Faded thumbnails work better by default than grayscale (though option to "desaturate" thumbnails a bit would help too)

TBH, I admit, I did not check options initially because there are so many extensions running that the small blue icon didn't even show up on Toolbar for me, it went into overflow. There was no "Options" option when I checked the addon in "Addon & Themes" panel, so I assumed there were no options for this addon, and browsed away oblivious to the fact that there were definitely options.

I hope that is fixed too. Options should be accessible from Addon and Themes section as well when checking extension.



PS: Still a very useful extension. Turning off these extra options made it actually more useful to me than when everything was checked by default.

It works, also has Import/export feature which seem like a great idea.

Does exactly what it says, and is incredibly useful when I follow my subscription feed.

Thanks for the Addon and for fixing it recently!

please update youtube has done so many changes and it doesn't fully work anymore, it still adds "watched" to the videos but it doesn't fade the thumbnails

edit: ty for fixing It I was already planning to change my rating don't worry ;)

Works great, only thing I'd like to see being added would be that it automatically marks all of your liked videos as watched too, there's a playlist with all of your liked videos maybe you'll be able to use that

Great extension however over the last few days it no longer works for videos in the sidebar or on the main youtube page.

Works on the subscriptions page at least as well on search results.
