It would be great if using groups we could link SONOS speaker with an Echo Show thus allowing the currently playing song on the SONOS to show up on the Echo Show now playing screen. Right now even if you initiate playback via Alexa on your SONOS speaker it does not display this screen.
As it is now you have to choose between getting currently playing information and the inferior speakers of the Echo Show or playing with the high fidelity SONOS speaker.
It is especially useful when you are hosting a party and someone is curious about what song is playing they can just look at the Echo Show and see what it is.
