This is a superb add-on and highly recommended. I always prefer visual cues to navigating large amounts of data and this provides an invaluable tool for email. I have gone out of my way to rate and recommend this and look forward to future updates.

This sort of approach could be really interesting for tracking the navigation, messages etc on a single website, such as Facebook as a Firefox plugin or Facebook App, or for other activity on the web too.
