It would be nice if on the screensaver screen, as a background, you could use images of the album of music that is currently playing. Optional - the possibility of basic music control from this screen.
I have 3 media players in my setup… A challenge would be which media player details to show?
Various implementation options are possible - at the discretion of the author. As a simple option, you can provide fields in the screensaver properties for entering the media player to follow and the source of the images.
