Because every time I STOP playing audio it defaults back to the pane 1 CC. And again I'll say it's not just music. There's lots of other audio around you know. Video, podcasts, books etc. Just cos someone has a different opinion than yours doesn't mean it's wrong. When I'm playing audio I often toggle between different speakers - Bluetooth, TV or whatever so having the pane defaulting to the audio controls when playing audio would just be simpler. I doubt anyone is likely to want to use the flashlight, turn off wifi or Bluetooth, so why the big deal about the possibility of it defaulting to audio controls?
Apparently now we're not allowed to suggest something isn't right for us and should just accept that Apple, and some other MR members are always right and we should just shut the hell up. Sort of defeats the point of people trying betas really if we're not supposed to find fault and suggest improvements. Terribly sorry for having an opinion on the internet that's different from yours. How dare we.
