[Avid-L2] [FR] Video Keyframe Display in Segments

See attached picture or this link:

Would be helpful to have a mappable toggle on/off button to display video keyframe positions in the video segments while in all modes:  Possibly they could simply be dots or diamonds. Timing multi-layer effect builds would be made easier and faster. 

Just thinking out loud.

Curious what others think.

Cheers,
