I'm using the DNG Converter app to save the ARW images from my SD card to DNG files, and would to save them directly to a CreateDate tag-based folder structure. I know how to use exiftool to restructure the files after dumping them all in a flat folder, but it'd be nice to have it done directly by the DNG Converter app.
Almost forgot, in addition to just being Nice To Have, the "Skip source image if destination image already exists" option won't work unless it can export to same layout as I use to keep my DNG files, so it serves a practical purpose too.
I don't believe the DNG converter is that intelligent. But, at least it's free.
