How about hiding the keyfile path & name? It seems a pretty big hole in the security to display it.

The default action should be:
Look for the keyfile in the last known location. If it is there, display the enter Master Key dialog box with only the Master Password box showing. If the keyfile is NOT where it was last, ask for the Master Password and the Keyfile location (but still don't show it).

Forgive me if this has already been suggested.
