Flats and sharps shown incorrectly in popup window
The flats and sharp radio buttons are shown incorrectly in the plugin popup window.
Flats should be above the natural line, and sharps below it. So the the fix would be to just swap the location of the "Sharp" and "Flat" texts in the popup window "Harp Pedal Diagram".
Please see this example diagram: http://www.animatedcreations.net/harp/images/pedalDiagram.jpg
