ThreadVis displays a small graphic in the header of your email that provides a visual context for the thread of the currently-selected email. Using TheadVis is a great way to track the history of an email thread.
To install ThreadVis:
After restarting Thunderbird, do the following:
In the currently selected email, you will see a graphic that looks similar to this:
Each message in the thread is represented by a dot. The oldest message in the thread is the left-most dot.
Some circles are spaced further apart than others. This provides an indication of the time that has passed since the messages have been sent or received.
Each person in the email is assigned a colour in the graphic. Each person in the email will have a coloured line under their name to indicate which colour shows their messages in the thread.
You can open each message in the thread by double clicking on one of the circles.
