digiKam from KDE3 branch : added a mime type pattern selection to the Album GUI status bar to filter album content based on file mime type.
Current options available are:
- All files (default)
- JPEG files
- PNG files
- TIFF files.
- RAW files.
- Movies files
- Audio files

This new feature can be used accordinly with the new Rating Filter tool and of course the Tags Filter sidebar tab.

Of course digiKam remember MimeType/Rating Filter settings between sessions.
