Cartographic help function

[AnjaSeckel]

If a cartographer has many labels in the map, then it is sometimes really difficult to identify the corresponding symbol. It would be helpfull to have a kind of combined selection function of feature and label. That means, if the user selects the "feature-linked" annotation, then the symbol will be also selected. This additional function could be activated or not activated. The placement of labels in the map will be easier and less errors will be made by the producer.
