Incredibly useful!

This app is simply invaluable for quickly testing and composing regular expressions, and seeing results interactively. It works very well, and has saved me so much time by not making me run scripts over and over to test.

This app easily pays for itself in one use!

I would like to see the rows in the search/replace lined up, so if you scroll one the other scrolls too, to keep them in line. Also, might be nice to see the matches $1/$2 and such color-coded in the search column so you can see whats being matched.
