I am just disappointed as the plugin misses a feature that you mention on your detailed screenshots. It was one of the main reasons why I purchased this plugin!
The function i am talking about is the "exit browser window pop up" - if user's mouse leaves browser window.
See screenshot here http://awesomescreenshot.com/0a33e89v35
I also attached the screenshot as image.
Please advice asap.
If i forget to setup anything i apologize my request.
