Rated 4 out of 5 stars

It works.
It's nice (not pretty, but nice).
No bugs so far.
Been using for close to 2 weeks now.

Certainly can come in handy when you have heavy searches going on.

This review is for a previous version of the add-on (0.1). 

Re:

The new version (0.2) has a splitter dividing the search results from the main window. I think you'll find that it now has a better appearance

The splitter also allows for the search results to be resized.
