On a related note, I recently discovered a useful Mail hint that I thought I’d pass on. Maybe everybody but me has known this for years, but the little icons that tell you whether you’ve responded to your emails (or forwarded them, or whatever) are useful as well as informative. When clicked, they will open the relevant email associated with that action. So if you’re looking through your mail archives, and want to know what your response to a given email was, just click the “I replied to this email” button, and Mail will open your response. Very cool, and very useful.
