Dynamic Background Image
Allow a Device to set/unset a Background Image (e.g. Album Cover or similar) during a Playback of some Media
I just configured the Chromecast Device with https://github.com/quintstoffers/neeo-driver-googlecast (as your Implementation is not really useful) and having the Media Image only as a Shortcut is not optimal/could be done nicer. The SDK currently allows no better way.
I'd like to only show somehow the Image when its set (e.g. when a Media is played). You could for Example use some of the wasted Space of the "Transport" Slide, make the buttons more narrow and use some Space to Display some Image.
