Waveform Brightness Control for the Audio Editor

In the Event-Desplay-Audio preference page there is a Waveform Brightness control for the waveform in the project window. I would like to see the same control for the Audio Editor.

I prefer a black waveform on a light color background in the project window and I would like that same to be carried into the audio editor without having to change the track color prior to using the editor.
