Geary - offline email client written in Vala for Elementary OS, which
attempts to bring the many GUI improvements made in webmail back to desktop
clients (eg threading emails and replies). It's fairly new (first release
2012), and they've had some challenges with their developer situation, but
those seem to have cleared up this year. I hope (and/or the developers of the
Pantheon fork) they do as good a job integrating an XMPP chat client and
calendar at some point as they've done on the email UI (or at least a better
job than Thunderbird ;).
Banshee - I've been using Mint a bit recently (naughty, naughty, I know) and
Banshee is one of the things I love about it. I does everything RhythmBox
does, but it doesn't crash as much (still does though), and it also displays
album cover art as if you had all your albums as CDs (or records) blu-tacked
to your wall, and you could scan across them and choose what to listen to.
0AD - now that I have some decent hardware to run it on, this is one of the
most professional-looking libre games I've found so far. Looking forward to
seeing the campaigns written, and might even contribute to that project when
I'm finished the book project I'm working on.
ownCloud desktop sync client - I have been using this with the ownCloud
server provided by OpenMailBox.org, to provide an excellent 100% libre
alternative to using DropBox for automated off-site back-up, and
synchronization of files between multiple machines. If I want to go beyond
the storage limit of OMB's ownCloud server, now that I have a desktop in use,
I can try running some play servers on it, including an ownCloud server (keen
to try running a GNU Social server too).
All 3 of these are in the Trisquel repos,
