提案/Suggestion
It would be useful if the list of items shown had corner icons annotating whether they can currently be upgraded, and directly upgrading it if tapped, or showing what’s missing if it can’t be upgraded.
現状/Current Status
Presently the list of equipment that uses an item only lists the equipment, but you have to exit and navigate back to that item in the equipment listings before being able to see if it’s even upgradeable.
