Background
When a template has no TemplateData or takes no parameters, and the template invocation has no parameters, the sidebar is completely empty and looks broken.
Screenshot:
Requirements
- Remove the no parameter message in main window
- Add a no parameter message to the sidebar as placeholder text. Only show if no parameters. Disappears as soon as a parameter is added and re-appears on re-open if all undoc parameters are deleted. Message text This template has no documented parameters and may be intended for use without them.
