Very glad you all like it.
We built the tool first and then did more in-depth research afterwards. We found WP Butler (thanks, Japh) and a few other tools, but thought we still fit a need in the WP ecosystem.

@Cam: I can't wait to see Omnisearch in action. We've been kicking around the idea of a "more results" page similar to omnisearch, but simpler and more streamlined. Maybe we can collaborate on a solution?
