I am extremely happy with how simple the plugin can be, if only careful attention is paid to detail. It seemed first that Marco the author could be really impatient with support if you read the supports, but if you are willing to sincerely go through the information he has provided he will definitely fix your issue as much as he can.
I do believe that he could make his documentation a little more "dummy" but thats okay!
The Plugin is fantastic and adds extra fields so easily!!! :D
