Some others bugs with the same feature request, i.e. duplicates: bug 204612 (and duplicates mentioned there, but not yet here: bug 342544, bug 357105).
Using drag & drop is not the only, but quite the most intuitive, way to get the attached message into a Thunderbird folder, i.e. as a normal message. Doing by (context) menu are others and mentioned in the other bug reports. So this bug title should be aligned to this.
