Great job, a feature-packed and strictly RFC-compliant extension.

From whati I've read in past reviews, this has never stressed enough: use another method if non-standard "signature" behavior is needed! (top quoting and signature before quoted text).
In those cases, "Clippings" extension does well; it allows placement of text particles selected among others (HTML supported too) with a keystroke.

Cheers,
