I have just released unique 0.3. The big changes are in the UI : the match results are now displayed using the source code as it is formated in the files instead of a flat list of tokens. It makes all the difference in the world :-)
The search process is still slow for projects that are not tiny, I'll see what I can do about that. I do have a few ideas on how to fix that - can't wait to see how they work out.
