Colors are dull, but otherwise a 5 star app

The app wrks fine and I can generate a regexp quickly. Would give 1 more star if the app is prettier.

Fast, simple and to the point

This app is awesome and easy to use. It not only does the job well, but helps me learn about regular expressions.

Love it...only 1 issue

A great app!!! Using it all the time now.

Would be 5 stars except for the fact that the text box does not scroll. If the pasted text is longer than the available space it sure would be nice to scroll.
