Love the sound, hate the app

I absolutely love the sound of the Sonos system! One of the best Ive heard so far. That being said, I would like Sonos to make an app or controller that works. I am constantly rebooting the system or shutting down my iPhone in order for the app to recognize the system. I would also like to be able to hear Sonos through headphones. I am a musician and often like to use my headphones to hear music in great detail and dont like to have to switch to a different app to hear it. In a perfect world, I would love to be able to play music simultaneously through my Sonos speakers and my headphones. Thank you, Sonos!
