Mr Unknown and other concerned parties may not be aware that the Winpilot optimizer provides a beep tone when it thinks you should open up your circle to recenter your thermal. It does a pretty good job of helping out if your attention drifts and you are no longer doing your thermalling work just right. In crowded circumstancs the WP optimizer can be used without looking down at all.

This audio tone feature is part of the WP Optimizer functionality that CN should be emulating. I'm happy to hear that the CN code is being actively improved but please don't relegate this to low priority.
