Nice, but some requests Rated 4 out of 5 stars

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?

This review is for a previous version of the add-on (0.1).
