I'm considering developing one but only if the interest warrants the effort involved. It would be a complete system. Customers request an RMA on the store side. Admins can issue RMAs, fire email templates with return instructions and properly manage return-for-exchange, return-for-refund and return-for-credit scenarios.
It'll be a big project, which I enjoy. I just don't want to invest 6 weeks of effort and be the only one using it
