Review for TB Header Tools Extension by pe4
Rated 4 out of 5 stars
With TB Header Tools Extension its possible to add notes at the header of messages .
The addons "ColumnsWizard" and "Mnenhy" display the added notes at the threadpane (separate column) and at the header of the message pane. I like this possibilty.
