Topic: cancel order vs delete order
in sales_order_entry.php i think more appropriate is for
$cancelorder = _("Cancel Order"); to be
$cancelorder = _("Delete this Order");
since that's exactly what it dose. It delete the order/quotation from your system.
"Cancel" mean that if you edit some items but then decide that you don't want the changes to apply (yet), you'll click cancel order (because that's how windows works) and you end up with deleting your file... It happened to me a few times.
