Performing a conversion (e.g. "1 metre in feet") only shows the result. It would be good to also show the full source unit to reassure that Kagi/Wolfram Alpha has interpreted the query correctly.
This was prompted by the following query:
Here I don't know if Kagi has used Bulgarian Lev, which is the unit I wanted, or as the first result suggests, Latvian Lati. Fortunately the answer was correct but I had to manually verify that since I couldn't trust Kagi's result because of no other provided feedback and the misleading first result. If Kagi showed the input unit that would make it clear it is outputting the answer correctly, and help clarify what e.g. an unknown currency code may mean.
