save_edit.module in Save & Edit 7

Save & Edit (http://drupal.org/project/save_edit) Provides a button that gives users the option to Save a form they are working on, AND return to the editing form in one step.

I find this quite usefull when entering a very long blog post, and my thumb hovering dangerously close to the mouse button that will take me "back" and lose all my entered changes/data.

No Kittens were harmed during the creation of this module.
