I really, really, like this add-on and have been waiting for something like it for quite a while. Ever since IBM showed a proof-of-concept for this I have been drooling at the prospect of my email client incorporating it.

I think ThreadVis has pushed me away from Mail.app and toward Thunderbird permanently.

The only downside is that it does not yet work with Thunderbird 3.x.

** UPDATE **
I have been talking with the developer and he knows about the problem with "virtual" (saved search) folders and it should be fixed in the next release. Also, it should be 3.x compatible. That will correct both of my major problems with ThreadVis and will probably move me to start using the TB 3.x beta much more.

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!
