Download the S1 controller from the web site, and use it to control your S1 components? Continue to use your S2 controller for the other devices?

Sorry for asking this silly question. I just had to scroll down to find the S1 app section on the download page.
Its sad but I am starting to grow less find of Sonos. And I dont recommend it to my friends any more :-(

(inspite of having 13 speakers.) Maybe this lack of good faith was the reason for me to not being able to find this obvious thing.
