Sorting in an effective way of working through a lot of back orders. We have orders that are being pushed in manually by the client and these recieve priority over older orders that have an older order number. Adding sort by option to screens where it is not availble already, would greatly help. We know it's possible as some screen are doing that ;-)
If this can include Product Qty or the option to remove 0 stock on the products screen too in refernce to filtering / sorting.
