As someone who is behind on videos for a lot of the people i'm subbed to having a way to sort videos into "up to date" and "not up to date" is really helpful but anyway you could add some sort of page bookmark thing So something like a button you can click when you hover over a video like theadd to queue or watch later buttons so if i was finished adding the videos i was behind on to my watch later playlist and at the top of the page i could bookmark the last video and the next time i went to update my watch latter playlist it would remember where i last was in the collection "not up to date" and take me to that part of the sub box rather then me having to stroll all the way down myself also it would be super helpful in cases where i forget what video i last added was also sometimes i miss it andstroll pass due to thumbnails looking a like so anyway you could add this bookmark thing?
