In Kleopatra, there is a useful feature that allows users to create key groups—collections of certificates (keys) that can be selected as a single unit for encryption. Instead of manually choosing multiple keys every time, users can simply select a predefined group, and the message will be encrypted for all keys within that group.

Additionally, key groups help in managing trust levels more efficiently. Instead of assigning trust to each key individually, users can set a single trust level for the entire group.

Introducing this functionality in GpgFrontend would significantly improve usability and efficiency for users handling multiple recipients.

Thank you!
