XnView Software

Suggestion for XnView Shell Extension.

Show another "thumbnail" instead of row with properties and add option to show custom information there:
[x] properties/size
[ ] date (file/EXIF)
[ ] EXIF/IPTC/XMP *

for mp3 (audio):
[x] bitrate
[ ] length
[x] mode-mono/stereo/joint stereo
[x] ID3 Tag v1
[ ] ID3 Tag v2

and for videos:
[ ] bitrate (for video/audio)
[x] length
[ ] frame rate
[x] codec

...

Or show is as several rows instead of another thumbnail, as option maybe.

Edit:

* change between the basic image/file info, EXIF, IPTC, and XMP with the mouse button - or/and show EXIF/IPTC/XMP info in submenu
