Please add design for media control buttons to gnome shell
Since by default gnome-shell does not expose any mpris control buttons I would find it great to have some official proposal for an potential implementation in the future. Right now there are extensions that could serve as an inspiration: https://github.com/JasonLG1979/gnome-shell-extension-mpris-indicator-button
Especially considering the mobile efforts this is some element that is surely important and therefore this would be a great opportunity to bring this feature to the desktop shell too. I think for consistency with mobile the notification area would be a great place, but I am not entirely sure.
