Wrong. This is an option, not all headers are emboldened. Hence the 'bold' option in the editor, this is what its for.> Viewing a mail: > http://grahame.angrygoats.net/images/custom-mail-headers-view.png The header "names" should all be bold, as they are with From:, Date: and similar. This goes along with the previous comment of the CheckBoxes in the GtkTreeView being used for enable/disable instead of bold.
