I just found your software yesterday and it's impressive but I have a concern that I'd like to share.  You say this is not based on Opentcart but I find that impossible to beleive and here's why.  Using Beyond Compare to compare folders and files to Opencart files there are way too many lines that are the same to beleive that it's not copied in parts.  It's pretty easy to see what's been changed and one cart has copied from the other. 

The problem goes to credibilty lost and you seem to have a great cart but I think it's wrong not to give credit where it's due.  It's hard to regain trust once it's lost.  I value your work but this will affect your success.  Demming said "the greatest losses in business are unknown".

Everybody makes mistakes.
