I'm so happy with that plugin. I tried other similar plugin before and it doesnt work, but that it makes the difference! Because I wanted to make a search filter step (my customer is an autopart dealer) so I needed to put a car model vehicle in the search box and that it needs to maintain through the following steps. He was so kind and he solve my problem. That plugin should help lot of business, just try it.

Also he promise to put an ajax live result! So he will update the plugin soon with new features!
