Why the decision to store edits in sidecar instead of the app’s library? I’m sure there’s pros/cons that were considered, so curious how the pros won out.
Sidecar files (like XMP) are the industry standard for non-destructive RAW editing - they maintain file portability between different apps and preserve your original files. Library-based approaches offer better performance and organization but create vendor lock-in and complicate backups.
Great, so if I use an app that creates XMP files, this app is going to create a second sidecar called rrdata. So I guess I could have amended that to the original question on why create a different sidecar than the images’ default.
