Well some suggestions, largely bugfixes, would include:
1. Recognise the MIME types application/pkcs7-* as well as
application/x-pkcs7-*.
2. Don't choke if message is signed by more than one person (multiple
SignerInfo structures).
3. Support multiple email addresses in certificates (emailAddress in
subject name and subject alternative name) and display them (subject
alternative name isn't displayed if I recall).
