Primary Panel
The NetBeans APIs give you access to the Options window in two different ways. In the first case, you can add a new main panel to the Options window. Using this approach, your module will add a new 'primary' panel to the Options window, similar to the 'General' panel or 'Editor' panel shown in the screenshot above. Your panel will, just like these panels, have a name and an image in the top of the Options window, together with its settings in the body of the panel.
