Did smarttube have custom feeds? I only saw playlists (where you add videos to them manually) and the ability to pin individual channels to the sidebar.

What I have in mind is an option that lets you scroll through the recent content from a group of channels (ex. cooking, travel, self hosting, tech review, etc.)

Very cool! Have you explored running this on an Android TV at all, since that’s what I was thinking of trying this on. That way you can flip through channels without needing to deal with login on TVs. Also I don’t think YouTube supports making feeds for channel types (ex. Cooking etc.), whereas an RSS feed would make it possible

I went to grab Bobby Tables and found this new variation
