This is a really nice plugin. However, you actually have to purchase it to get the real thing without "demo" splayed on the screen. Also, when you do purchase it for 40-299 Euros, you get only a few months of upgrade.
This seems to fly in the face of the WordPress plugin culture. It is certainly not clear that this is a demo, and it's really expensive as plugins go.
Not a fan.
