Revolutionises message handling Rated 4 out of 5 stars

Great, it really shows the whole thread in an overview and helps me a lot!!

I'm giving it only four stars because some things may still be improved:
- show contact picture
- allow to send the reply later (it's sending immediately if you use fast reply)
- some issues with text size (even though it's okay for me now, I had some issues before on other computers)

That said, let's not forget that it revolutionizes (replaces) the way the messages are shown so some incompatibilities (eg when using an addin to display contact photos) will be inevitable.

This review is for a previous version of the add-on (2.6.3).
