Mr. Hartmann, why do all of these Digital Asset Management functions have to be in one app?
Editing raw files to produce excellent JPEGs, which is what the Nitro Photo app does very well, is quite a different skill and process than managing photo file storage and metadata.
I now own or have in the past used many apps (like FastRawViewer, FileLoupe, ApolloOne, Photo Mechanic, Bridge, DigiKam, A Better Finder Rename, not to mention tools provided by the Apple operating system itself like Image Capture and rename in Finder) to handle my DAM needs.
I prefer choosing my own way to work with photo files. And would not want to distract the developer from producing excellent JPEGs.
