Would like to see the ability to control the centre channel and up firing speakers via the app. I am finding  even after trueplay I want to adjust the centre speaker on some content.

You may want to try speech enhancement.

Yeh always have that on, but been watching some old bond films and really needed to up the centre channel still, could do it on the old q90 soundbar I had. Would still be very helpful to have that option.

I want the Sonos immerse! Can be the heart of a true modular wireless surround system.
