Every property in the property grid has, apart from its value, also a symbol indicating if the property is bound to the configuration or not. If the symbol is missing, the property is not depending on the configuration in any respect.

A mark indicates that a property depends on the configuration directly, and

- has a default value (red mark with white square inside), or

- its value is defined in the parent configuration (pink mark), or

- its value is redefined in the current configuration (red mark).

A green mark indicates indirect dependency on a configuration - this means that the property does not influence any other settings or behaviour of the system, such as a Note (which is just a plain text).
