Sharing bangle 1 UI idea

I haven't used it in practise, but in the demo that it seemed reliable enough, given the button isn't too large and a the tip of an index finger covers both touch areas. You might have to be a bit more careful than usual though, when pressing it, for accuracy.

I was browsing the source of some of the 'launch' apps on the app store and realised people are already using this feature for 'center touch'

// Screen event
Bangle.on('touch', function(button){
  if(STATE.settings_open) return;
  switch(button){
    case 1:
      prev();
      break;
    case 2:
      next();
      break;
    case 3:
      run();
      break;
  }
});
