Hello

I don't know if it's the right place to ask, so sorry if..

I would like to implement into my site the posibility to make extra charges (surcharges) for payment methods (for credit cards in my case). I see that option is available now in 4.1.2 version and could be great to implement into my 4.0.18 version. Can somebody point me to the right files to modify? I have beyond compare but there are so many unknown modifications so i better ask here first before anything

Thanks
