  // This mode attempts to offer a single knob full navigation which is a bit contorded due to LMS UI's 
  // principles. Left, Right and Press obey to LMS's navigation rules and especially Press always goes to 
  // lower submenu item, even when navigating in the Music Library. That causes a challenge as there is no 
  // 'Play', 'Back' or 'Pause' button. Workaround are as of below:
  // - longpress is 'Play'
  // - double press is 'Back' (Left in LMS's terminology).
  // - a quick left-right movement on the encoder is 'Pause'
  //
  // The speed of double click (or left-right) can be set using the optional parameter of 'knobonly'. 
  // This is not a perfect solution, and other ideas are welcome. Be aware that the longer you set double 
  // click speed, the less responsive the interface will be. The reason is that I need to wait for that 
  // delay before deciding if it's a single or double click. It can also make menu navigation "hesitations" 
  // being easily interpreted as 'Pause'
  bool enable = 1; // Enable/disable
  int32 delay_ms = 2; // optionally set the delay
