Makes sense, thanks for the response, I really like the tool.

I think one area where Namegrep would benefit is to offer a few more examples to try out. As a "hacker" myself I immediately understand the power of the tool, but still want to see a few more interesting regexps that actually yield some worthwhile domains.

That and inserting a subtle horizontal divider in the result search everytime I press the search button (while in regexp mode). That way, at a glance I can see where my previous query ended and my new one began.

Awesome work!
