Rated 4 out of 5 stars

This, in combination with the addon Mnenhy, means you can remove the lame buttons from the headers AND you can display the exact headers you want to display. The only problem, and why I give it 4 stars, is that if you hit the - to collapse the header to one line, then hit the + to renable the header, it is blank. You have to select another message, then re-select the previous message, to see the headers again.

This review is for a previous version of the add-on (1.2.2).
