Hi
In storyboard mode VP only shows track 1 and references it by thumbnails of equal length not ike the timeline where length relates to clip duration.
Although I am sure that NCH could implement separate thumbnail storyboard tracks for the overlays, their relation to the main track and to each other would necessarily be lost. However, the option to toggle the single storyboard display to show the individual overlay tracks might have some use as it might save having to scroll along the timeline to find particular overlay tracks that require attention.
