Rated 3 out of 5 stars
After expanding, the email recipients are not sorted in alphabetical order. Could you please do that, so it is easier to find the recipient to remove?
I just call the expansion function, that Thunderbird uses internally just before sending the mail and write all addresses back to the dialog. If there's some functionality to sort recipients, maybe from another add-on, I could try to include that, but currently I don't have much time for further development.
It is more important to update the add-on to work with future versions of Thunderbird, which I hope to achieve in the next weeks or months...
