This module allows you to turn off the Menu section in the node creation/edit form per node type. This can be a very nice usability improvement since typically only the "Page" node type is used in the menu tree.
Note that the functionality that this module provides has been built into Drupal 7.
This module was originally developed as a proof of concept related to this D7 usability improvement suggestion: #436836: Make visibility of Menu section in node form configurable per node type
