The current default sorting in the backend is in some random illogical order. This is terribly bothersome - a perfect activity for a masochist. :-\
In which file can I force the default sorting in order from the most recently added product? - I want to see this normal setting every time I open the product list
PS. I manually enforced this in the database by modifying the link to the product list:
index.php?option=com_virtuemart&view=product&filter_order=virtuemart_product_id&filter_order_Dir=desc
