Have you ever to subscribe to updates to a specific playlist within a YouTube channel, instead of all the new videos in a channel? Unfortunately, YouTube doesn't support playlist subscriptions. But, YouTube has an API... YT Playlist Notifier is a progressive web app that allows you to search for and subscribe to updates to playlists. You'll get a browser notification when new videos are added to any playlist you're subscribed to.
