The Export to OBJ format... differs as the whole model (not just what is visible in the 3D view is converted to an obj file) since it is located under the 3D view menu I thought new users might think only what they see in the 3D view is converted to an obj.
Sorry, it's not true: only furniture checked as visible in the furniture list will be exported in the OBJ file. Thank you db4tech, you gave the final reason why I won't move the Export to OBJ format... to an other menu.
