no more single frame "view"
looking at the forum: https://forum.kde.org/viewtopic.php?f=265&t=170841&p=445063#p445063
seems that the single frame "edit" is missing on latest versions of kdenlive. (the maximum zoom on timeline is not reaching a 16/9 form factor for the single frame... and thmbnails are not displayed)
