Make Magento orders of a *state* (thus all attached statuses) visible / hidden on front

sales_order_states.xml

<!-- Update config node /config/global/sales/order/states like this: -->
<config>
  <global>
      <sales>
          <order>
              <states>
                  <[state_code]>
                      <!--
                        Available state_code are:
                        . new
                        . pending_payment
                        . processing
                        . complete
                        . closed
                        . canceled
                        . holded
                        . payment_review
                      -->
                      
                      <!--
                        Set <visible_on_front> as required (1 is default).
                        @see app/code/core/Mage/Sales/etc/config.xml
                      -->
                      <visible_on_front>0</visible_on_front>
                  </[state_code]>
              </states>
          </order>
      </sales>
  </global>
</config>

<!-- Example to hide orders with "canceled" state: -->
<config>
  <global>
      <sales>
          <order>
              <states>
                  <canceled>
                      <visible_on_front>0</visible_on_front>
                  </canceled>
              </states>
          </order>
      </sales>
  </global>
</config>
