I'm still currently playing with this extensive plugin. It is a freemium offering of the authors' Toolset plugin, which includes a display engine and form processor. Because it is freemium, the authors are very committed to it, as it is a gateway to their other products. I have posted support tickets, and their support is amazing, even for the free extension. This is a major free plugin that doesn't look like it will be going dead in the water anytime soon. And even if it does, it has an export feature that lets users use the created custom types, etc. without the plugin installed.
