6. Child element: `ToolDefaults`

ToolDefaults stores annotation-tool defaults and feature toggles. The root-level flags are visible in settings_en.xml; many tool-specific children are emitted/parsed by the external AnnotationTools serializer.

Common attributes observed in code/sample XML:

Attribute	Type	Meaning
`StickyTool`	boolean	Keep the tool active after one use
`ShowPropDialog`	boolean or int	Whether to show a properties dialog. Most tools use boolean; the note/text tool sample uses `2` and that numeric meaning is external/ambiguous.

`Color`	int	Main RGB color
`BorderColor`	int	Outline RGB color
`FillColor`	int	Fill RGB color
`BorderWidth`	double	Stroke width

root/PrintDefaults ...

The repo source confirms that it is loaded and saved as part of settings.xml, but the exact inner attribute list is not visible in the checked-in sources. For admin authoring, the safest approach is to capture a generated sample from a configured installation if you need this specific block.
