Rated 4 out of 5 stars

This tool helps a lot on navigating through mail threads and is really cool and intuitive to use.
BUT: There is always a warning from thunderbird (command not successful, mailbox does not exist).
I'm using the 3-row-view in thunderbird so there is not much space left for the messageheader. Therefor I would like the tool just to consume the space it needs for the graph and not to take the full width always.

I had read about this visualisation method, but seeing it in action is even better!

The extension seems to work without problems, and the only thing it would need are some graphic and interface refinements.

Great work!
