I always keep my email default to plain text.
This addon lets me easily switch how I view the emails.
But version 3.0.3 of this addon doesn't follow through, and let me print how I see the email... So for me, this is not very useful. Until that functionality is added, I give it 1 star for starting off in the right direction.
