Please provide a better visibility of data stored in one part of Thunderbird also in other parts of the app.
What I'm thinking of:
- I can save birth dates in the address book, but I can't see them where it would be natural to have them: in the calendar.
- The OpenPGP key manager is kind of like an extra address book. Show an icon in the "real" address book next to a mail address if there is an encryption key stored. Provide a shortcut from the address book to the corresponding entry in the key manager.
