I knew this would happen. I recorded a video while a new version was being released. Development is moving so quick on this project that any review will be outdated the minute it gets posted. That's O.K., though. You can watch my vid for the overview and check the links for the latest features.
Springboards, which I mentioned in my video, but didn't understand, can be seen in their full glory here.
LemoNZ's Matricks video demonstration can be found here.
