Not sure what some of these folks are complaining about. I thought what the plug-in did for free was extremely valuable but needed the additional features. So I did not see features getting stripped during an upgrade since my version was paid. Other than some sorting/reporting weaknesses that are likely easily remedied so sales teams can more easily report and track, I think this is a completely viable solution to ad management. If author continues to grow it, he may have an enterprise level solution on his hands.
Please keep up the great work!
