Somebody should make a module out of this (or a setting in core) -- better than having this in a custom module deployed with every Drupal site.

This module scans the currently installed contributed modules and themes, and determines if they have been changed from what was originally downloaded. The interface will then show you exactly what has been changed.

This is primarily a developer tool and should never ever, don't even think it, be installed on a production site.

This also includes Views URLs taking a node as argument (node/%/yourview), in short, every URL that is based on, or extends, an existing alias.

The program creates a default comment management view that uses Views Bulk Operations and Token Actions to create a view of comments that allows you to search, edit, and delete comments and also send mail to selected comment authors or node authors about their comments.
