Useful addon ... Rated 5 out of 5 stars

It is very useful to have maximum view of message body but a little difficulty to identify TO and CC mail ids in two line view. I suggest (or request) to highlight TO mail ids (in bold or some other color) to differentiate between CC mail ids.

Thanks.

This review is for a previous version of the add-on (2.0.0). 

Already implemented

In the two line header mode the CC addresses are displayed italic and the BCC addresses italic and underlined.

I didn't want to use bold or a different color because then the CC/BCC addresses would appear too important.
