Make relevant settings accessible while sleep tracking

I always get really frustrated when I want to turn on/off binaural beats in lullabies or lucid dreaming audio when starting sleep tracking, because I have to cancel tracking, unlock the phone, open the app and search for the right settings. So I suggest that all the relevant settings which don’t influence wake up time should be accessible through the pull-out menu on the left while tracking.
