The Node Menu Parent module extends the "default menu for content" setting provided by the core menu module by allowing a specific menu item to be selected (not just a top-level menu) per content type.
Example
Imagine we're creating a site for a business that will have a section describing the products they offer. We've got the core content types, Page and Story, and we've added our own content type called Product. Then we add a few pages under the Primary links menu, like so:
<Primary links>
Products
Support
About Us
Now say we've decided that every product should have a menu item under Products. However, core Drupal's menu settings only let us choose a global default menu for content, such as Primary links. That means when we go to create a Product, the "Parent item" dropdown under "Menu settings" defaults to Primary links so every time we create a product we have to manually select Products as the parent item. This is tedious, easy to forget, and unnecessary extra clicking.
