I am aware of how to sort it manually, and that is what I do.
Please add the feature to set the default sort. My preference would be show open invoices first, and then sort the invoices by descending due date.
I think almost everyone would prefer the sort I just described. Customization really isn't required - I would be happy if there were just two modes: classic and smart (smart would be what I described above).
Regards,
