TVSubs - Add TV Shows to Youtube by TestPenguin

Inject external items into YouTube's Subscriptions feed that look like videos but link elsewhere.

Features
• Follow any show by name and TVSubs will pull the newest two episodes via the TVMaze API.
• Cards display real air dates, durations, and fallback artwork so they blend in alongside YouTube uploads.
• External links are clearly labelled and open in a separate tab

How to use
1. Install the extension and open the TVSubs popup.
2. Enter a show name and the destination link you want (official site, streaming app, etc.).
3. Visit https://www.youtube.com/feed/subscriptions and refresh — the newest two episodes per show appear as external cards.
4. You can unfollow shows or change their link at any time from the popup.
