I have been using this extension. It requires some learning curve and need to dig into code to understand some of the functionality due to lack of enough documentation(though in the site there are documentations to some extent but when searching for solutions to issues, not able to find them).
I would suggest to open the forum to public as it is now being closed. I cannot post the issues into the forums. Hence I face difficulty.
However, overall I would like to congratulate the team on bringing out such a promising extension.
