limited setting

The app does not allow switchng JBL xtreme to mono sound, which substantially improves speakers performance to next level. This would be convenient as there is no stereo effect on one speaker anyway (as the left and righ drivers are too close to each other).

The app is more or less only for people who own two speakers, and surprisingly in paired speakers mode it allows switching each speaker to mono sound mode (in connected stereo mode).
