The new triple style description need more clarity Rated 5 out of 5 stars

According to the description, (>>) should appear only when there are multiple people in the email message and (>>>) should only appear when a mailer group is involved. However, in my use, I see (>>>) not only for mailer but also for non-mailer messages with multiple people listed and see (>>) for the same as well.

Example: email message with say, gets tagges with (>>>), even though there is no mailer group in it. On the other hand email message with mailer group gets tagged with both (>>) and (>>>). Hence the confusion.

So, this is where it not clear how this is suppose to work. May be you can use an example to illustrate these two cases for clarity. Thanks

This review is for a previous version of the add-on (0.7).  This user has a previous review of this add-on.

I don't understand what exactly needs to be fixed. What you describe is exactly the intended behavior. The idea of the add on is to make it easier for Thunderbird users to identify important mails. That's why it distinguishes 3 three types of mails, the personal level: Mails only sent to you (usually those are most important), mails sent to you but also to others and then mails that are sent to a list, but not directly to one of your mail addresses.

My understanding of a review is that you rate the add-on against its description, I was hoping the description makes the purpose of the add-on clear enough.

I like the idea with colored arrows, I'll add that as a feature request to the bugtracker.
