Never say never. Offer us a really, really big check and we might consider it! But ... We'd really prefer not to have different versions of our product for different customers. Our goal is to constantly produce new features that are valuable for the largest possible number of customers and, by doing so, to keep costs down for everyone. Customization isn't cheap for you or us. So, our current policy is to maintain a single code base and improve the system based on feature requests and voting by customers in our feedback forum. If you want something new, suggest it here and see if your peers agree! :-)
