OK, as promised, here's a cool little project you can prop up with Docker and get a Channels optimized M3U playlist and EPG for Pluto. This differs from other Pluto M3Us as it utilizes the extended tags we created to let you add richer data and art into the UI allowing for what you see in the screenshots I posted above.

All ya gotta do is launch this docker container and it will sit on a port and serve out the M3U and EPG. It updates every 3 hours.
Be sure to get the new builds on TestFlight so you have the changes that help make these look better.
