More importantly be able to use sonos in automation and scenes to setup buttons on switches that support scene control like heatit z-dim or heatit 8 or 4 kanal wireless switch + fibaro switch or dimmer to control sonos 😉👍

The possibility to select Sonos Favorites in app and in automations and shortcuts/scenes.

Need a scheduling feature, may be part of automation or a separate function i dont now.

Unless you have a good way to quickly enable/disable this it can be extremely annoying. We had something similar set up. Now imagine this.

You are the resident smart home geek in your household who is the only one capable of setting all of this up. You are now on travel for work abroad. It's a public holiday at home. Your house is full of guests, sleeping on inflatable mattresses in the living room. Your spouse calls you at 05:45 in the morning. You cannot hear what she is at you. Partly because you are still asleep and partly because the 70-ies disco playlist is playing at full crank in her end. The only managed to snooze the Sonos and manually change modes to turn the lights off. The guests are scared to death. 9 minutes later the snooze kicks off and hell starts again. She calls you again asking you to get the fudge out of bed and remotely disable this monstrosity of bed. My zzz now = 0. No further evidence needed ;)
