A few weeks ago after looking at the taxonomy views integrator a reader posted about how helpful sub path alias is combined with url alter and of course pathauto. Full Disclosure: tested path alias extended, it seems more robust, but must have missed something as it didn’t flow right off the shelf…
Use Case: when a user logs in I want them to go to a URL based on their user ID and immediately begin editing the URL. Pathauto will give you token replacements to do stuff like survey/[user:uid] however when you go to edit the node it typically reverts back to node/81948794387/edit making it difficult to reference. You could use something like drupal_get_normal_path($path); to do this, but that's not going to make it pretty on the url line, and it's just kinda messy.
For those interested in a video it's here - no reason to get too excited though - it really does just work - tested against 40,000 nodes and they're all happy, you should be too...
