What is PanelBuilder?

PanelBuilder is a potentially generic term. Without more context, it's difficult to provide a precise explanation. It likely refers to software or a system used to design and configure panels, which could be user interface panels in software applications (creating layouts with buttons, text fields, etc.), control panels in industrial settings (designing the arrangement of physical controls and displays), or electrical panels (specifying the components and wiring within an electrical distribution board). Its common use would depend entirely on the specific type of panel it is designed to build.
