Yes, for S/MIME Smartcards you can do a "gpgsm --learn-card" directly. I think 
"gpg --card-status" would also have worked.

Yes, you can look in the files, they basically say that "A key with this 
keygrip is available on the smartcard with the ID X"

We totally agree with that. Our goal is to have it "plug and play" where 
ideally we could also fetch the public key from a smarcard also for OpenPGP.

For S/MIME Gpg4win-3.1.12 will already add this autmation to GpgOL (https://
dev.gnupg.org/T4877 )

Improved Smartcard support and GUI for that is currently one of our 
development priorities.
