Marlon created toolbar button icons (bug 104502), as shown in the topmost and the bottom-most rows of the GIF that I'll attach. At some point, we want to implement bug 144402, and then we will require additional icons, those that are shown in rows 2, 3, 4 of the attached gif. (Currently, the image contains old temporary icons.) The requested icons are: - send button with a broken key, which should indicated: "Sending encryption is requested, but currently not possible" - security toolbar button, indicating that encryption is requested, and everything is fine, because valid certs for all recipients are available. - security toolbar button, indicating that encryption is requested, however, we are unable to send encrypted, because for at least one recipient, we don't have a valid cert.

Old plans. Let's make new plans and file new bugs if we ever go back to this. wontfix
