Thank you for your input and feedback. I've passed your idea to our colleagues from the product team. I voted for it, as we're all eager to have Chromecast improved 😉
I was looking at switching to Deezer from Spotify, but I currently stream my music via a Google Nest Hub 2nd gen controlled via Spotify desktop app (Mac).
If there’s no way to conveniently (i.e. not via web browser) control my music from my desktop, I don’t think I can make the switch, sadly!
I don't really know why you mentioned this "feature" because based on the thread there it's completely useless to my described use case? Did I misunderstand?
