Feature description

An option in the /Settings/Content/ tab to show only similar channels subscribed to Newpipe would make it much easier to consume channel content without necessarily being the most recent videos posted. A tab in the search with this filter would be interesting.

Why do you want this feature?

Difficulty watching old videos from subscribed channels, or lack of recommendations from subscribed channels in the app
