I want to insert my
custom .phtml code in one of the magento core page. To be more specific i want to put my code in order to be displayed in
<my-server-name>/index.php/admin/sales_order/view/order_id/1 page. For the sake of example i put the code direct into the
/design/adminhtml/default/default/template/sales/view/tab/info.phtml and now the view looks like in the capture.
My question is how to achive this task but without touching the core file ?
