Hi,
It would be very nice if there an option to limit "Now Playing" widget to only Spotify or iTunes. Because I see "blob://..." text on widget when I play YouTube video in Safari.
I really wanted to echo my support for this kind of feature, or at least something similar to the default Touch Bar where you can choose between multiple "now playing" sources.
But yeah more than anything, I just want a reliable button that I can tap to start/stop Spotify without it getting conflated with some random autoplay video somewhere that's stolen focus!
BTT uses the macOS standard "Now Playing" information, so this probably won't help you if an app got a "lock" on that.
