User-Agent: Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.4; en-US; rv:1.9.0.4) Gecko/2008102920 Firefox/3.0.4 Build Identifier: Often I will find that after I hit either reply-all or reply, and am typing my reply, that I wish I had hit the other button instead. Gmail's web interface offers a nice option to switch between 'reply' and 'reply-all' after one has started composing a message. Would love to see this in Thunderbird. Usecase: 1. User hits Reply to a message 2. App displays Compose window with to: sender, and toolbar button 'Reply All' 3. User starts typing reply 4. User clicks 'Reply All' button 5. App adds all original recipients as CCs. If user has entered additional recipients, they are preserved. If a collision exists between the additional addresses and the added addresses, no duplication shall occur. 6. App changes state of button to read 'Reply' instead of 'Reply All' 7. User clicks 'Reply' button 8. App removes all original recipients from current message recipients, with the exception of the original sender. Any additional recipients entered by the user are preserved. All dupe checking/matching to be performed via exact string matching on email address portion of recipient. Reproducible: Always

thanks... (I searched for "switch" but not "toggle").
