I've been a happy Droid owner for 8 months now, but the one thing I really miss about the iPhone is the media controls "on-demand", meaning a home button double-click brings up a popup with play/pause-next-prev buttons. In Android, it's a bit of a pain to do those tasks without having a permanent home or lock screen widget. I guess what I'm looking for is an app that could live in the notification shade whenever the music player is running, but that contains music controls in addition to the track info. Would such a thing be possible? Would Android even allow an interactive notification like that?
