@winzou Does Sylius fully support multiple shipment already? How does store admin / customer create multiple shipment?

@umpirsky I think we can implement the [UI](https://moqups.com/kayue/msOO5jyq) in `shipment_show` page, instead of order page. And I suppose clicking "Ship all items" won't change the order status in this case. 

(and we can add a custom "ship order" button in order page in our internal project as a workaround)
