Hi Craig, it's possible to organise images into subfolders and also view all images on a single contact sheet. If you right-click on the parent folder, it offers a couple of options to open all subfolders in one sheet. When I'm sorting using subfolders, it's mainly to easily add customised metadata to images, but I also find it helpful for culling, as all similar images are kept together. If you could provide me with more details about your current pain points in your workflow, I'll see if I can think of a solution.
All the best,
Alex
