sortable columns?

Hello there,

Thanks for this neat plugin. However, I need to ask you something..

How can I edit the code to make the columns in “Order Product” sortable?
Also, although seeing every unique item in the order separately helps, shouldn’t there be a “orders only” page, or option? What I mean is just the orders, not the products in them. This way there may be an organized way to see total orders, which customer ordered how many times etc.

Again, thanks for this

Deniz
