Good Great script. Minor problem: Seems like something in the statistics isn't quite working as intended. My average videos viewed per year is only about 6x the per year, instead of 12x.

Good Scrolling Page I need to switch tab Mark will be effective. If you don't switch the label, the mark will not appear.

Good Works great as advertised. I'd love to see a future option to hide watched videos altogether. I suspect you'd need a button to toggle between "No Markup", "Marked", and "Hidden" Thanks!
