As of the latest TestFlight beta and server pre-release, List layouts are now available for Pesonal Sections.
You can now use the same List layout that Playlists and Recent Recordings use with your own Personal Sections.
Additionally, you can now choose to use List layouts when expanding your content rows via the More buttons. This is especially helpful for rows that are based on videos or episodes, as the Flow layout for these can get a little awkward if they're all from the same show.
