They used to have handheld controllers, the CR100 and CR200, back before everyone carried around smart phones. I’m not sure they want to get into that business again, as I don’t think it sold well.

There are some 3rd party options out there though.  Google “sonos wall control”.  You can also mount ipad or android tablet.

There is at least one forum member (and perhaps more)  who has written software that can do this, running on Pi devices, and providing that ‘now playing’ screen you seek. I personally don’t have the gumption or time to delve into it, but I certainly admire the skills I see from these folks.
