+		A new <code>Modify..</code> button is added to the <em>Execution Environments</em> section of the <em>Overview</em> tab of the Manifest Editor.
+		       At the same time the <code>Up</code> and <code>Down</code> buttons are removed.
+		       Because technically the order is irrelevant, the specified environments are always sorted in ascending order.
