i think you shouldn't bother posting here again!
the problems you have describe are just how you think something should work!
they are not bugs at all. just functionality you want adding!
so instead of paying for an extension or hiring a developer to code your specific needs you thought it was acceptable to post it as a bug report and use works like "need serious overhaul" even though you have no idea in coding terms what serious overhaul means! coding select products to have free shipping would only take a few lines of code without having to overhaul the whole shipping system!
you just want to over emphasise the importance and hope i will run around after you to get these features implemented you selfish idiot!!!
Do any requests for enhancements ever get adopted? I'm new to the OpenCart community, and I want to know if such reactions are common.
