I really like this add-on. It significantly enhances review of search results.
In 3.0, the options window was so large I couldn't get to the bottom of it to submit changes. However, that's fixed in 3.1, which is, at this writing, still in the sandbox awaiting approval. (You can still download it, but you have to sign in first).
Good job by a very responsive developer. Quick and effective fix.
For now, it gets one star. Fix the options window and I'll upgrade that substantially.
