I suggest that you consider adding this feature to a future release of Thunderbird. Thanks, Manu Reproducible: Always Actual Results: none Expected Results: Being able to edit a message like outlook. This facility is useful especially when receiving an HTML email but you only care about the text content, or adding information (e.g. mailing list subscription information might not be complete,...). Working with persons from Russia and China, changing the encoding to western is useful, because in those encodings the text appears bigger or smaller in your email client (Thunderbird/Outlook behave the same here) than the other messages.
