Thanks for the response! That makes sense, though a more customizable trading system is a much-needed plugin that I haven't been able to find elsewhere, so you'd have the market cornered!
I'm happy to chat if you're open to doing a commission to add probably just the first and second feature (though I am but a poor therapist / video game dev!) If you're interested, feel free to email me at moonsoulgamescompany@gmail.com. If not, no sweat : )
