I bought this for a commercial real estate client and assumed I would have to really customize it to make it work for their needs. But it was as simple as modifying a language file or two and a CSS file and voila! The extension is the smoothest, fastest, feature-filled extension I have ever tested. Beautiful work, and fantastic support, a very classy extension and worth every penny. I can't wait to see what they develop next, because this was an excellent experience.
