What others say about the Bluetooth Loudspeaker app

Appreciate you for your great app, but I cannot use it outdoors, because it conflicts when a call comes. So I have to pull out the earphone-Jack. Please set an option to stop the program during phone-calls. Please make it more systematic, play the app in background in notification-list control. And so on. Waiting for the next version. Ps: please set an option-box for your app, I don't want this app come along with my player-app. This is very annoying. Conflict with the phone-calls is also annoying.
