Today I realized that playlists allow you to set a custom background for their headers.
I've set a header for one of my favourite playlists and was going to figure out what the proportions are so that I can edit the image so as to prevent it from squishing so much, before realizing that whatever image I set persists for ALL playlists.
How can I set a playlist header for only a single playlist? I don't want this image to be used for any other playlist. I wish to set a different banner for each playlist.
