Doesn't do too much for me. IMHO It would be a kickin' extension if it integrated with the T'bird compose environment. E.g., providing it with some of the functionality that rulers provide in word processing programs - setting tabs, bullets, leaders, etc. (including working with tables)

This review is for a previous version of the add-on (0.3.2008120101).
