I am using PM6+ build 5216 on a Mac running iOS Catalina 10.15.7.
I have certain folders on my HD that I use for specific purposes. In this case, I put cropped and sized images that meet posting guidelines for specific on-line forums. When I do a "Save as..." using preset, it sends the modified image to the folder and opens that folder as a contact sheet. Works perfect, and I've been doing this for years.
The contact sheet defaults to sorting the images by Filename in ascending order. I always change that to sort by Modification Time in reverse order so the newest images are first. Is there are way to get PM to open the contact sheet with the desired for order, rather than default to Filename? I tried an arrangement, but that seems to only show the images that were present when the arrangement was made, not including any new images, plus I still need to select "Arrangement" from the drop down list.
