I am starting to really grok the drupal module release system. I just packaged up and released a little utility I have been using as a module. Find URL Alias (http://drupal.org/project/find_path) adds a "Find alias" tab to the URL Alias admin page, so you can type in an alias and jump directly into editing/deleting the alias, or viewing/editing the node. It also tells you if you have multiple aliases to the same node (a SEO no-no).
If this doesn't sound useful to you, I bet you aren't using pathauto :)
