Clicking on the Toolbar icon opens a UI to quickly switch the Addon ON or OFF, or open the options page. 4. Each header item has several options to adjust (see add-on's Options page for details) 5. You can add several header items and active or inactive them separately. 6. An example in the options page shows a tutorial on "How to add a custom header".
