-- Single image view mode with keyboard navigation
-- File system navigation
-- Multi-threaded thumbnail generation for responsive UI
+- Browse images in a directory tree with file system navigation
+- Multi-threaded, cached thumbnail generation for a responsive UI
+- Single image view mode with keyboard-driven zoom, pan, fit and navigation
+- Fullscreen viewing
+- EXIF/IPTC metadata panel (camera, exposure, ISO, focal length, dimensions, …)
+- Geo location with a clickable OpenStreetMap link when an image is geotagged
+- Edit image captions (written to the IPTC Caption-Abstract tag)
+- Lossless 90° rotation (updates the EXIF orientation tag, pixel data untouched)
+- Move images to trash and delete files
+- Right-click context menus (including copying file paths), also in fullscreen
+- Configurable keyboard shortcuts
+- Preferences for background color, thumbnail cache size, dock locking and layout
+- Path entry field with autocomplete
+- Translations (Danish included)
+- Supports every image format provided by the installed Qt image plugins
 
 ## Requirements
 
 - C++17 or later
