How to display more Order's info. in Admin.?

Hi, has anyone managed to display more info. on the right side of the Admin->Customers->Orders page? To make postage calculation faster, I need to be able to see the following info. on the right side for a selected order:

• Weight of Articles (even if Shipping Option is free)
• Shipping Address
• Special Instruction (if any)

Appreciate your advices much.

For comments, find the section in the:
/admin/orders.php

where the code reads:

// indicate if comments exist
      $orders_history_query = $db->Execute("select orders_status_id, date_added, customer_notified, comments from " . TABLE_ORDERS_STATUS_HISTORY . " where orders_id = '" . $oInfo->orders_id . "' and comments !='" . "'" );
      if ($orders_history_query->RecordCount() > 0) {
        $contents[] = array('align' => 'left', 'text' => '<br />' . TABLE_HEADING_COMMENTS);
      }

And change to read:

// indicate if comments exist
      $orders_history_query = $db->Execute("select orders_status_id, date_added, customer_notified, comments from " . TABLE_ORDERS_STATUS_HISTORY . " where orders_id = '" . $oInfo->orders_id . "' and comments !='" . "'" );
      if ($orders_history_query->RecordCount() > 0) {
        $contents[] = array('align' => 'left', 'text' => '<br />' . TABLE_HEADING_COMMENTS . '<br />' . $orders_history_query->fields['comments']);
      }

For the weight you would need to either customize the orders class in the Admin or add a function to calculate the individual weight depending on attributes etc.

For the shipping address, you could probably pull that from the orders.php to see how that is gathered and use that as a guideline ...
