As part of the Navigation documentation T19736, the documentation should be revised. Suggestion:

Revise the Qt Gui tutorial (see ...\Modules\IGT\Documentation\doxygen\IGTTutorialStep3.dox).

Suggestions:

• Extend the explanation. What will be done? Add screenshot. Rephrase "More information", cause this part contains the actual tutorial step.
• rename "User manual"
• be consistent with the example plugin name in the workbench, code and documentation. Decide for a name without the step number (this migth change) and don't call it module as it is a plugin
• replace the icon with the current one
• Maybe disable the possibility to change the tracking device during tracking (nothing is and should happen there)
• ...

At the moment, the new structure is not included in the master, have a look at the branches of T19736.
