It would be nice to have support for groups of photos in f-spot. Then you could have one group for each slideshow, gallery, cd or portfolio. Perhaps those sorts of groups could even be their own subclasses of group with subclass specific functionality.

The difference between a group and a tag is that a group is a collection of photos . The main ability gained by having groups is to be able to order the photos in the group as you like, for example to tell a story with a slideshow.

You could also add the ability to place photos into a group at import.

One thing to keep in mind is to make it clear that the group only contains references to photos and that deleting a photo from a group won't delete it from the catalog.
