This extension allows you to quickly EDITyour orders of the page by Chaining them, that is, when editing an order, there will be 2 buttons:
1. Edit Previous (if there is one)
2. Edit Next (if there is one)

and a Checkbox:
1. Save on Next/Prev (checked by default)

- that is, if you edited this order and you just want to edit the next one without saving, just uncheck it and the next order will appear without any savings
- if, you wanna save and there will be an error, the current order is still displayed with the error attached, so no wrong data will ever be saved


The previous/next order is exactly the previous/next order of the order you're editing of the page (that can be filtered, ordered, sorted,..

P.S. When filtering by Date Modified, please pay attention that there is an error on the Opc sources (admin/model/sale/order.php line 623,
it says
$sql .= " AND DATE(o.date_modified) = DATE('" . $this->db->escape($data['filter_date_modified']) . "')";
when it should be
$sql .= " AND DATE(date_modified) = DATE('" . $this->db->escape($data['filter_date_modified']) . "')";
