Very useful Rated 5 out of 5 stars

The idea for this addon is great, very useful for who is receiveing lots of e-mails every day, and must to know which one is personal. My suggestion to improve it is to allow the user to config the symbols used to indicate the personal level, or give many choices to chose from, making it more intuitive according the personal preferences.

This review is for a previous version of the add-on (0.5).
