False alarm... but new idea
Sorry false alarm... My "New Products for March" title went walkabouts and at the same time turned on new products listing on... and not having sleep for the past week or two made me get excited and believed it was what we were after.
However seeing that the new products listing followed the categories all the way down means that we should be able to steal some code from there then take out the function that asks if the product is new and replace our main listing with it so it digs out to the deepest categories. Possible?
