I thought this was going to be a replacement for Watchmarker, but having to manually click each video as watched, instead of it being automatic, is a complete dealbreaker.
I like the idea of the extension, I just wish it synced across multiple devices. If I mark something as watched on my home pc, it doesn't link to my work pc or laptop. Other then that it's a great.
зачем этот огромный красный квадрат на каждом видео?!
Great extension! Please just shrink the Red Square since it visually very annoying. It is almost taking 1/6 of the space in the video preview on the right side of the video suggestion. It is useful to grey out a marked video, but not when you still have to watch it. So, shrink it by a lot, or make it more transparent, or just make red the actual white square and remove the big red square. Thanks!
My previous extension for this was just disabled by Chrome. This looks useful, but it will be incredibly tedious for me to go back and manually mark every video I have seen in the last few years as watched! (It isn't registering a single video as watched automatically.) Why can't this read when the video has a red bar under it, or if it has been liked, and automatically mark those as seen? Please? I couldn't find any other place to leave suggestions.
It doesn't look like in the pictures, it changed. However it's been the best one I could find. You could actually mark that you've watched the video which is nice as you can skip it if it's been marked as watched.
Request for Marking Shortcut Support. After the update, the marker is not displayed on the related video on the right side of the playback video.
Very useful extension! I wish it was on firefox too!
really great extension I just wish the tagging was automatic
I liked the idea, but assumed it actually HID videos from search results that I'd already seen. Still having to scroll through reams of stuff seen - just grayed out using this. I guess it's useful for others, but for me with a lack of simple operators in youtube "search" - even negation (try to stop it bringing up terms you don't want, there may be a way but I can't find it) and it throwing back stuff incessantly I've already seen - I've been trying anything that looks remotely like it might make Youtube behave vaguely normally. Now if you could do that....... :)
