I mentioned the rearranging/differing layouts, as I don't particularly like the concept of the notification toggles being a 1:1 linear of my QS panel.
While I'm delighted to have the individual components interchangeable between the two, and using the same code for simplicity, I don't want my media controls on my QS panel, especially at the top for them to show up on my notification panel where they're supposed to be. The WiFi toggle and AP toggle I can live with on my QS panel, but a whole button devoted to the "Play" function on my music control? Seems like a ginormous waste of space to me.
The concept behind the QS panel is to provide feedback about the settings of the phone. WiFi shows if it's connected, disconnected, or off entirely, by its icon, and the AP name that appears. It shows the current user by their profile, it shows all kinds of settings as they currently are, through visual feedback. It's great for that. Adding a play button seems very out of place, there, and inappropriate.
Obviously just my $0.02, and I know this isn't how the team has designed this feature going forward. But perhaps my comments make sense enough to take pause and consider redesigning it. If not, I'll shut up and either write my own patch or accept defeat and use a notification through Tasker or something, but I figured I'd provide feedback. Either way, I'm all for a simpler codebase, so please don't take this as a "I hate it entirely!" post.
