I've followed this component for over a year now and must say that its evolved. For simple structures it saves a lot of time BUT for more complexe features its not ready imo. Reason? Lack of proper documentation. I've bought a 3 months subscription but I stopped working with it after 3 days because of this. Its a pitty that such a potential component lacks timesaving documentation.
Then the support is worth a 5 stars rating too, I had some wishes which could be fixed within the current release and some which could not. Dima clearly showed me how to reach my goals and was prepared to discuss about new ideas and implementing them in future release. Forum posts got answered immediately...So great software, great support and great work, use it and get happy.
Feel free to ask about new features, if I have enough time, I'll try to do that, or think of it ;)
