It is a shame that users are leaving low reviews when many of these problems could be solved by just contacting their excellent support team. Adding a second or third monitor (using your iOS device) for a few bucks with this app is invaluable. I also like that if you turn off your iPad or it happens to lose connection, the desktop client creates a little virtual monitor inside another window window, so your application window locations dont get lost. Great work!
