			<description>
				Adds a control to the bottom panel (together with Output, Debug, Animation, etc). Returns a reference to the button added. It's up to you to hide/show the button when needed. When your plugin is deactivated, make sure to remove your custom control with [method remove_control_from_bottom_panel] and free it with [method Node.queue_free].

			<description>
				Adds a custom control to a container (see [enum CustomControlContainer]). There are many locations where custom controls can be added in the editor UI.
				Please remember that you have to manage the visibility of your custom controls yourself (and likely hide it after adding it).
				When your plugin is deactivated, make sure to remove your custom control with [method remove_control_from_container] and free it with [method Node.queue_free].

			<description>
				Adds the control to a specific dock slot (see [enum DockSlot] for options).
				If the dock is repositioned and as long as the plugin is active, the editor will save the dock position on further sessions.
				When your plugin is deactivated, make sure to remove your custom control with [method remove_control_from_docks] and free it with [method Node.queue_free].

			<argument index="3" name="icon" type="Texture2D">
			</argument>
			<description>
				Adds a custom type, which will appear in the list of nodes or resources. An icon can be optionally passed.
				When given node or resource is selected, the base type will be instanced (e.g. "Spatial", "Control", "Resource"), then the script will be loaded and set to this object.
				You can use the virtual method [method handles] to check if your custom object is being edited by checking the script or using the [code]is[/code] keyword.
				During run-time, this will be a simple object with a script so this function does not need to be called then.
