Add/Edit orders in admin panel

The admin should have the ability to add/edit orders in the admin panel (add/remove products, change shipping/payment methods, etc.), and add a new complete order.

Thank you.

Yes I think the same. I can imagine that there's often the need to change an order. For example when you need to remove a product that's been sold out since and don't wannt to cancel the order because of that.

Then after the edit, a new invoice should be sent to the customer and the order status changed to 'updated'.
