Tracker now has a much nicer and improved UI to go hand in hand with new services being indexed like Evolution emails
The tab view provides a nice breakdown by service type of the search results complete with a hit count in each tab (services without hits are not shown)
Also any searched email can be double clicked and the email will be opened in evolution and shown in its own window.
Expect a release some time this week as I iron out the few remaining bugs/issues.
I'm sure a few distro's will start considering shipping tracker by default in the coming months now that the all important email indexing is just about done and especially as we tackle more and more services which will come thick and fast now.
