Очень хорошо работал, но после последнего обновления Windows 10 перестал работать в ленте рекомендаций. Можно ли вернуть эту возможность? Было очень удобно. А теперь стало хуже на 50%. Звездочки ставлю с учетом того, что раньше он работал очень хорошо, а теперь "сломался". Использую версию 1.3.2. Спасибо. 22 июля 2025 - все поправили. Большое спасибо. Опять стало очень удобно. Все звездочки. Могу ли написать вам на почту, если снова что-то сломается?

This is an okay standin for Watchmarker for Youtube, but a way to automark watched/liked videos would make it five stars. I just cannot go back through and mark the tens of thousands of videos I've watched individually.

It was perfect, but suddenly it doesn't work in my subscriptions feed. Idk why, in home works, in watch later works, but in the most important page doesn't work. Something for fix it?

This is great! I LOVE the manual marking but I'm with Francesco Ricigliano and his review. The check mark box square is Way too large and distracting. Either an adjustable box transparency feature or a much smaller check box. But otherwise I think it's perfect! UPDATE 7/2025: Thank you for listening to your users! Love this app!!

Excellent extension, as I am sick and tired of frequently being shown on a home page videos that I have already seen. Like, c'mon, youtube, with all your resources you can't do that yourself? Even when I select "new to you"? A small question for the dev; do you think it's possible to add an option to also *HIDE* marked videos from appearing on both home and subscription pages? I mean, sometimes it is just annoying to see greyed-out rectangles. Like an option for users, to whether see watched videos as greyed out, or completely gone from their page? Kudos for the extension!

Works well! Wish there was an option to automatically Mark any video you've watched, like the old Watchmarker for Youtube extension which Google just killed last week.

It really needed me to be able to manually select and manage the videos I watched. For someone, this may be the reason for the low ratings, but I needed something I could control myself. The red bar that automatically marks the video you've watched on YouTube is incomplete and sometimes disappears. Similarly, the automatic marking supported by other extensions that follow this is the same. Plus, if you accidentally delete your viewing history, everything will reset.. I found this because I'm tired of all these things and I'm using it very well. I'm grateful to you, and I want you to keep it for a long time. I hope you can control the transparency of the thumbnail.

I love that in this extension, you can manually select which videos you want to mark as watched and which ones you don’t. I previously used Watchmarker, and it sometimes added videos I didn’t want, making it difficult to remove them from the watched database later. Additionally, it has an excellent GUI. I give it 11/10!
