This is just a public complaint, because I'm too lazy to go file a bug report or something. I use F-Spot for managing my photos on my Ubuntu desktop. It's kind of cool and mostly does what I would expect it to. One thing that really bothers me though is how, when you are flipping through pictures, it shows each one blurry first, and then it come into focus. I suppose this is done for some kind of effect, because I've never seen any other photo software do this (gthumb and eog, to name a couple close competitors), but it drives me insane. I have bad eyes and have worn glasses since I was about 6 years old. Every time I flip to a new picture they strain to focus on it until it fully comes into focus on its own. If there is any way to make this stop, I'd love to hear about it.
And since I'm complaining about F-spot, I'll mention one other major beef I have with it (I've got a bad cold and am grumpy, forgive me). When you import photos, you choose a directory (or camera). When you make that choice it starts displaying all the photos in that directory and has a grayed out inactive button that says import. After a while it finishes and you can then highlight a subset of the photos in that directory and click on import. At this point, though, it has already imported every photo from that directory and your selection does nothing. The import button merely dismisses the import dialog. There seems to be no way to import only selected photos from a directory or camera. This is just dumb.
Phew. There. It feels good to get those off my chest. There a few other little complaints I have with f-spot, but overall, I really do like it.
