Better Subscriptions for Youtube™ by OsaSoft

This plugin adds a checkbox to the YouTube Subscription Feed that allows users to toggle whether or not they want watched videos to show up in the feed.
The aim of this is to make navigating the subscription feed much easier and intuitive.

Current features:

• Hide videos that are marked as WATCHED in Subscription feed, YT Home and Channel Videos page
• Mark videos as WATCHED to hide them from feed
• Mark all as WATCHED
• Hide videos in subscription feed automatically, once you start watching them
• Hide Premieres until they are available to watch
• Hide Shorts
• Hide empty sections (Today, Yesterday, Last Week, etc)
• Collapse sections to navigate to older videos more easily
• Show videos that have been hidden
• When hidden videos are shown, unmark videos as WATCHED to show them in feed again
• Settings page with configurable options
