The screenshot was using the Sawfish default theme (called "Crux") and Adept-Premier (available at gtk.themes.org) with a few modifications to suit my preferences.
This should be the conclusion, of a sort, of LoserJabber-related features. Everything else requires a bit more effort, and isn't as interesting. I'd like to work on some other projects for a bit, I think... something that would benefit humanity more.
Or maybe I'm just lying to myself because I'm disappointed in the number of LoserJabber users, and I'll realize this and add some whiz-bang GNOME/Advogato support in the next release. :P
Either way, I'd like to do something more impressive with my spare time.
