It's not. Tags are nice, but to do what I am looking for would require the creation of Hundreds of tags, which is tedious and counterproductive. This would be a lot more useful than tags. The ability to change the Subject line of any message received. More discussion can be found at: http://slashdot.org/comments.pl?sid=212872&cid=17320818 Reproducible: Always Steps to Reproduce: 1. Receive an E-Mail for a specific thing that has a generic subject 2. See that there is no way to easily organize it 3. Actual Results: Nothing Expected Results: A subject line that can easily identify what the E-Mail contains. An idea for implementation (copied and pasted from the thread above) I just want to follow up on how this might be implemented, since I think it's a great idea. Thunderbird could allow you to insert an additional header, perhaps called X-ModifiedSubject, where you would enter your modified version of the subject line. When the messages are listed, the X-ModifiedSubject would be displayed as the subject if it existed. If there was no X-ModifiedSubject line, the normal Subject would be displayed, but in a different color from the X-ModifiedSubject, so you can easily distinguish the ones you changed from the ones you didn't, and not confuse anybody when talking about the email on the phone (since the sender won't know you've made the change). When you reply to an email containing a X-ModifiedSubject, Thunderbird should have you choose between the new subject (more descriptive) and the original subject (vague, but more recognizable to the recipient) when generating the subject line of the reply. I suppose any searches you do on the "Subject" field should search both the Subject and the X-ModifiedSubject. For example, your mail headers might contain: Subject: WebSite X-ModifiedSubject: Need to update copyright date on website That way, when you browse your mail listings you see "Need to update copyright date on website" instead of just "Website," and you can easily tell what the message is about without clicking into it and reading the whole thing.
