Should be a must have feature beside default S/MIME Noté 4 sur 5 étoiles

Having a S/MIME certificate is hard but having a GnuPG keypair is easy. On the other hand using OpenPGP signing without using PGP/MIME messes the email message for those who doesn't have OpenPGP compatible client.
So the best part of this add-on is "OpenPGP Signing + PGP/MIME"
