I originally invested in Channels for the DVR and virtual channels features, intending to keep my library curated on Plex, but as my family used it we have really enjoyed its versatility. The library features have started to get better, thank you developers. The one thing I would like to see is flexibility on the art images. Poster art sites like https://theposterdb.com and https://thetvdb.com have lots of options to customize your library but the 4:3 or 16:9 ratio crops most images. I understand the rational for the 4:3 ratio for TV images but I would be happy with an option to select whether I want the image cropped or left full size and black bars added to the sides to fill out the 4:3 ratio. Id be even happier to have the option to display TV series in my Library with just a 2:3 aspect ratio.
I apologize if this is elsewhere I did search for a similar feature request.
