Hi @Atmosius, welcome to the Sonos Community!
I think this would be a good way to control your system though I personally don’t see this happening anytime soon: I’m happy to share with the relevant teams for their consideration, however.
If you’re looking for a way to control your system from your watch now, then you might be able to find a third-party app that does so. I can’t provide any recommendations myself, but Googling for third-party Sonos watch apps or looking through the Sonos Community should help with this.
Also, if the music service you use has a smartwatch app and supports direct control, you can control your system with that app. I had a look at Spotify, the music service I use, and it has a WearOS app with Spotify Connect support, having the controls that you’re looking for, such as play/pause/shuffle/etc. While not all services offer this, it would be worth looking into as well.
I hope this information helps, and if you have any further suggestions or recommendations, then feel free to share them here!
