Nice, but some requests Noté 4 sur 5 étoiles

Thanks for this nice addon, indeed functionality that should be in TB by default.
Some requests however:
- currently the only option it gives me is adding the signature at the end, could it provide an option to insert the signature at cursor location?
- can it put an <div class="moz-signature">...</div> around the signature so it renders as usual?

Cette critique est pour une version précédente du module (0.1).
