Great tool. One of my best friends. Export feature is one thing I really wish it had.
This is a good basic GREP graphical user interface. I'm using it on Mac OS X 10.8.3 (Mountain Lion). One aspect that I found better than other GREP GUIs that I have tried, is that you can copy the results. That way I can paste the results into a text file or report. One function that I tried, but didn't work for me was the Ignore Case checkbox. As long as the checkbox was checked, it found nothing. With the checkbox unchecked and the search text having matching case, it worked.
