Lumen 1.2 makes big folders easier to work with: - Filter: type in the new search field (or press Cmd-F) to narrow the grid by filename as you type - Sort by Date Captured: order photos by the date they were actually taken (from EXIF), not just the file date - Batch rename (Pro): select any number of photos and rename them to a numbered sequence like "Trip 01", "Trip 02" in one step - Live refresh: photos edited or regenerated outside Lumen now update in the app instantly, including changes inside subfolders
