It was working perfectly for the first 2 weeks where Watched Videos would Fade, but recently those same Watched Videos would suddenly show up CLEAR or UNFADED.
I love this remake of an extension. Everything is great about that but I wish there was a button to add the video to the watched history, currently you can only delete the video from the history. The perfect feature to add would be adding syncronization but this is a difficult task to do I guess. I found a fork in github of the original watchmaker extension but the sync is broken there with supabase and it is not udpated, and the extension itself was kind of broken.
As other people say, it still doesn't always work on the recommended videos list on right side of any video. Sometimes it works only on the ones shown, but then you scroll down to see more suggested videos but these do not get marked as watched even if you have seen them before. It does not work properly as it used to, it's one of the most useful YouTube extensions but still it's not working 100% yet (as of version 1.0.10). I hope an update fixes this soon.
Very good extension.
Muitas vezes eu prefiro fazer cursos com vídeos do youtube do que comprar alguma coisa, mas nem sempre o youtube marca direito o que eu já vi, principalmente se passar muito tempo, tipo 1 ou 2 anos, então me serviu demais, obrigado.
This extension is a good replacement for the old Youtube Watchmarker, but since last youtube update it stopped showing 'watched' in short videos when you use any kind of sorting
Thank you so much for this, is there somewhere we can donate if we feel the need?
