The report Sales By SKU has the only option to sort the products as by SKU.
This report could be used as a "best sellers" report (by category, by brand etc) if only you could sort by Quantity Sold instead.
The data is displayed there so this shouldn't be too hard, just needs to sort the display by that field. As it is, if we have hundreds of products in a results list we would need to scan down visually or Export to CSV. Of course it's possible to sort an export, but it would be nice to just be able to do it on screen without going to separate software.
