As stated in the developer comments: I didn't invent the feature to forward inline. It's a standard feature of Thunderbird to forward a single message inline.Bug 401479 is a feature request to add an option to forward inline multiple messages as a single e-mail. Maybe you can add your comments there and vote for that bug if you want that feature added to Thunderbird.
