I’ve recently decided that Playlists is the best way for me to organize things like “Marvel Cinematic Universe” movies and “Disney Animated”, etc. based on my set up. It would be a nice (small) feature if we could edit the thumbnail that appears on the playlist homepage with a picture that represents what’s in the playlist. For example, I would use the MCU logo and the Disney Castle logo for the two aforementioned playlists.
Early 2021 clean-up: duplicate
The requested feature can already be achieved using collection!
