Youtube Subscription Feed Cleaner

There should be a popup that comes when you open youtube asking if you want to unsubscribe from a specific youtuber since you either haven't watched a specific amount of there videos or haven't watched there videos for a number of days. there can also be a "Don't ask me again" button in case they want to stay subscribed but doesn't want to watch there videos.

This may not be a big problem but sure is one that should be solved.
