Displaying all products on sale with exp:resso store?
It looks like it's not possible to pass an on_sale parameter to the products tag. This would be useful for pulling back a list of products that are on sale. Unless I'm missing something you currently have to pull back the full list and check the on_sale conditional, which is not as efficient and throws out the count and total_entries variables.
Could this be added to a future version if it's not already possible to do this somehow?
