I don't want to pour any dirt on these guys, as it's really a great idea and I really like it. But it was a big downer when we donated to be able to download the files for VM, and it turned out to be far from what the video shows. They provided great support and refunded the money, and I don't complain at all. Just want to warn everyone that the demo video is not up to date and you should use the demo link to see what the latest code is like, not to be upset once you get it.
Again, nothing wrong with it, as long as you are OK with the preview link. But video is what really makes you want to get it, but it is not the same with what you actually get after donation.
