We are testing on Woo a new commerce site.
We have added some user roles, UKSales and Worker.
We have restricted the Worker role so when they log in they only see the orders page, but we only want them to see the orders from the UKSales customers. Nothing else. They can then update the orders as per normal Woocommerce as needed.
It could be in the form of a php file, but module would be a little slicker, especially if later we want to add another 'Worker' for another group at a later date.
