Please, could anyone tell me where to switch the sorting order for products at category page.
I need default descending order for "In stock" parameter. I want customer, who chose in-stock sorting to see first products in stock, and out of stock - last.
So I need to set default choice for "in stock" - descending order. And for product names I still prefer ascending as default (from A to Z).
How could I manage different default styles for sorting options? Any advices are very welcome.
