TIM L. Very cool idea - and very useful, once you get the concept of it. I used it to do a pretty complex find and replace on website I was working on. Took me a while to get a handle on how to perform the search and replaces I wanted, but it was worth it - saved me about 2 days of really boring manual changes! Watch the tutorial that comes with it - otherwise I might never have understood how it works! (Version 1.0.2)
