Sometimes I reply to an email when the subject of that email is not relevant. When I do this, I delete the subject line and the body and write them both from scratch. My reasons for doing this are:

1. Sometimes I find it easier to remember subjects than contacts, so finding a relevant email is quicker than finding the required contact.
2. Sometimes I want to email a group of people and finding a previous email on which they were all recipients is quicker than listing all the recipients on a fresh email.

When I did this on Gmail, which was my only mail client for many years, the email with the new subject would start a new conversation. On Thunderbird, the behaviour is different. The new email is part of the existing thread.

Is there a way to change the Thunderbird behaviour to be like Gmail, i.e. thread emails by reference until I change the subject, then start a new thread?
