This add-on will no longer be supported when Thunderbird 78 is released in a few months, unless enough people commit to supporting continued maintenance of the add-on to make it feasible. To show your commitment, please visit https://www.kickstarter.com/projects/jik/rewritten-add-ons-for-mozilla-thunderbirds-next-release and make a pledge. As a bonus, Kickstarter supporters of this and my other add-ons will receive significant discounts on add-on licenses.
Adds menu items allowing the user to toggle the Replied, Forwarded, and Redirected flags on existing messages.
This add-on was created by Christian Eyrich. He is no longer maintaining it, and his version is no longer compatible with recent versions of Thunderbird and SeaMonkey, so Jonathan Kamens has taken over maintaining it. Thank you to Christian Eyrich for all his work on this add-on!
