I want to create a clone of the Notebook feature and would like to do it without copying the files and doing a find/replace on the text. Is there an easy/built-in way to clone a feature and provide it with a new name?
Try http://drupal.org/project/features_clone. From the project page:
Features Clone is a Drush command that allows quick cloning of a Feature. It can be used to rename or fork (e.g. to start a new feature off of an existing one) a Feature installed on a Drupal site.
