I like that the input rules are flexible enough to understand most web forms. The inputs are very similar to regular expressions. If you don't know what that means, this is not the form-filler for you.

What would give this 5-stars, is the ability to export form rules, AND support for multiple profiles (Home, work, School, etc).

The "Rules" window on the options page is too small. Even with a 24" monitor, I can't see more than 9 rules at a time because they are in a frame.

There is no way to sort or group rules. There might be several ways web designers chose to ask for state. I'd like to be able to put all the state rules together, for instance.
