I can't tell if this plugin is even still active or not. Their website gives no information about the plugin and the github they send you to is equally uninformative. The plugin does not generate a preview of any sort and the support information is pathetic. The plugin developer promised a tutorial and it has not been done in months.
On the bright side, attempts to buy the plugin failed since there seems to be no way to purchase it. So-perhaps what was initally a frustration is a blessing.
