Every minute, more than 500 hours of video content is uploaded to YouTube, and it is physically impossible to be aware of everything at once. And if you subscribe to a lot of channels, then even they can be difficult to keep track of.
Fortunately, there are third-party tools that can help solve this problem. One of these is the free cross-platform extension PocketTube, which allows you to create folders for organizing your list of YouTube subscriptions.
Sort the channels by topic, mood, or just by how much you're interested in them. Then you can watch the feed of the latest videos only from certain groups. The extension is available for all desktop browsers.
