Sorting out what stuff actually costs may be unnecessarily difficult for newer players. It used to be possible to tease this out of the old UI without actually having the building in port.
The blueprint window calls the resource collection window. It currently shows labor hours available but does not display any calculations unless a building is present.
My suggestion: Allow this to display calculations even if collection is not available. This will allow players considering contract offers to readily look up what the resource actually costs in both Reals and labor without having to own the building in the port they are visiting.
