Connection ordering

Since version 0.9, when registering a connection type, you can set the 'sortable' flag:

	p2p_register_connection_type( array(
		'id' => 'posts_to_pages',
		'from' => 'post',
		'to' => 'page',
		'sortable' => 'order'
	) );

This will make the connection rows sortable via drag-and-drop. The ordering information will be stored in the 'order' connection field and will automatically be used when calling p2p_type( 'posts_to_pages' )->get_connected().

Note that since reciprocal connections are only stored once, ordering will only work one way.
