I love that you can organise images into a folder, but it would be great if you coud see images that have not been put into a folder and are just sitting in the generic "images and files" section. Maybe add an option to the "Show Archived" filter so that it is somethign like "Show Archived" - "Hide Archived" - "Show no folder" or similar.
Either that or add a column when you are looking at the top level "Images and Files" section that shows if the image is in a folder and what folder it is in.
