Under Settings we now have "List smartcard readers"
But to change the setting based on this listing a user has to discover that the setting is under "Kleopatra Settings -> GnuPG System -> Smartcard". This is not so nice when we could in theory just use a radio button next to the list of smartcard readers to offer such a selection.
The second Problem that this has is that many customers want us to hide the "GnuPG System" settings as they are too low level for most users. And when we hide it they cannot change the smartcard reader which can be important as we have at least one customer who does not use standardized readers and where each user would need to change the setting manually.
