Packing and shipping with fewer slips

Undo a Mark as shipped, see each card's spot on the order, and To ship lists the oldest paid order first, without test orders.

Undo shipped: marked an order shipped by mistake? Undo shipped on the order puts it back to processing, so it can get a label. The shipped email your customer already got stays sent, and no new email goes out. Orders shipped with a carrier label keep Replace label instead.
With MyParcel or Sendcloud connected, Mark as shipped on the order is a gray button next to Create label, and the bulk Mark as shipped says labels are the usual way.
Spots on the order: each line on the order page shows where its copy lies, like "Spot: Binder 1 · Page 4". Buyers never see it.
To ship starts with the order that was paid longest ago, and a page holds 50 orders.
Test orders no longer count in To ship or the sidebar badge. They can still get a label, and Create label says that label is real.
Labels stay inside the EU with Sendcloud too, as with MyParcel. An order going further can still be marked shipped by hand.
The parcel weight sent to your carrier leaves out items the customer withdrew.
