Comment 3 for bug 1502245

OK, the checkbox may not be re-filled if we load the default scene. However a value is placed into config.ini.
The other two, light and coords, are switchable via hotkeys. But OK, it may be meaningful for the coordinate display to have it as permanent option for researchers.

In general, there is some inconsistence around settings. Some are remembered when you set them, others only when you click "store defaults". I think we should get rid of "store defaults" (except for view direction/fov) and set values in config immediately.
