It is in development. Hopefully ready in a few weeks when version 4.0 ships. Keep in mind a lot of the responsive design depends heavily on the WordPress theme. The big change in the plugin is removing any “hard HTML” elements like table cells and replacing it with 100% CSS-driven design using divs and spans.
Pro Pack, Enhanced Results, Enhanced Search, and Enhanced Map all provide even more control over the UI elements of the plugin. To get a fully integrated responsive layout you’ll want to grab all 4 of those add-on packs.
Get them now before the upgrade fees go into effect and the pricing increases. Owners of add-on packs purchased within the past few months will get the 4.0 compatible upgrades for free.
