Pretty cool. One issue I've come across is that button doesn't show when navigating to another video. Tab needs to be reloaded. So to fix this you need to listen for the 'yt-navigate-finish' event. I've updated the background .js here:

Couple suggestions: - The text is aligned justified which looks pretty bad imo. So rather text align it left. - Add an option to reset the 'minutes saved' count
Thank you very much for the good rating despite the comments. To be honest, it is very unexpected and nice to see a proposal with a code example right away, it is the first time I see this and it is very cool! Thank you, I will include these improvements in the next update. If you have any more suggestions, let me know by email ogobel@icloud.com
