there was an example given to add a new panel and buttons to an existing butons or properites window in blender
but for this we add to make a new class for the panel and the button
why do we have to create a new classes to do that ?
i mean i tough that a class is an object by definition and is used to create objects
so a class is like a template to create objects and then you can use the fileds and methods defined in the class for the newly created objects
but here we need to create new class to do that why not use the existing class in blender
cause theses must already exist to create all the panel and buttons ?
