I asked a3Rev's support forums to add a Sort Results by variance (colour, size etc.) and sort results by price, a little bit like eBay, and my response was feel free to hack the the plugin to suit my needs and that a3Rev were not planning on adding such feature. This is fine accept how would I begin something so big? If anyone has pulled this off (or something similar) I would be grateful to know of your existence and if you are able to help then that would be greatly appreciated.
Please let me know how possible this is, and what I need to do.
