Do not show focus indicator in case motion detection is suspended: Motion detection will be suspended in case the diver is operating the OSTC using the buttons. In previous versions the focus indicator was shown even the motion detection was not active => may cause confusion. The indicator is now only shown in case the detection is active Added hystresis for switching between sector views: In previous versions small jitter at the angle signal could cause fast switching of the custom view. An offset has now been added to avoid this scenario
