Thanks, Michael. I’ve now set up a keyboard shortcut to delete all gaps at the same time.
Yes, I do sort by file extension to delete them, but I often do 5 to 10 videos edits per day and each requires about 20 grabs and, thus, even doing this takes time when you add it all up. I know lots of people have requested a ‘jpeg only’ option on the grab page. Hopefully they will add the feature request soon.
