提案/Suggestion
Give us a way to view what ore we are currently smelting, and give us a way to cancel driftsmelting it (discarding the current ore in the process). So if we are currently smelting a Cyan, but we really want an Amber, let us throw away the Cyan that might be at .3/5km so we can smelt the one we want.
現状/Current Status
It is impossible to view the ore currently being smelted, and it is impossible to change ore once it is smelting.
