Little tiny side note: F-Spot rules as a photo organiser: I can import my photos from the camera, tag them, print them, export them too photo albums, BUT there are two tiny issues:
* why cann't I start GIMP on a photo and automatically get a new Version of it when I save (preferable a separate version for each save operation)? or why can't I just say that photo 1 is a version of photo 2?
* why exactly does F-Spot consume over 250 Mb or real nonshared memory during photo import from camera and almost 150 Mb of memory at all other times?!?!?!!?!

grumble, grumble, grumble, must file bug reports, grumble, grumble...
