I think hinting the user which card to insert to for a card based key operation is a great feature I wouldn't like to miss.
There is a good chance that users will have multiple keys on different cards. If none of the attached cards contain a matching key this notice is very welcome.

In this respect the key stub as a memory entry where the private key was last seen, seems to be a good thing for me. 
But it is frustrating if you get ask to insert a different card even so a card inserted contains a matching key. 
Updating the stubs with „—card-status“ would work for me. An automatic check on all connected cards would be cool … but maybe slow ...
