Yes, that's still missing in Kleopatra. See https://dev.gnupg.org/T5334 which 
is the high-level task for improving the support for WKS/WKD in Kleopatra.

Sounds good.

That's what this mailing list is about. For more direct assistance we could 
also meet at the #kontact IRC channel at Libera.Chat.

I'm afraid that I won't accept such an MR. Using QGpgME Jobs is the 
recommended way to interact with GnuPG via GpgME. (Another way is via Assuan 
transactions, e.g. for smartcard support, but that's not an option here.)

BTW, I don't know your current status, e.g. whether you are a student, but in 
case you are interested: I'm pretty sure g10 Code GmbH would pay for your 
work. They are looking for developers and maybe even student workers.

Ingo
