Joomla Extensions Directory Link (if you can leave a review that'd be great!)
Custom DOCman SEF Router File (no longer needed if you are using DOCman 2.0 and newer):
Starting with the 1.5.6 release I am now including a customized router.php file for DOCman within the DOCMan List Plugin ZIP file. This custom router.php file will greatly reduce the number of queries needed to display a page when you have SEF enabled on your site.
If you'd like to take advantage of it, simply copy the router.php file included in the DOCman List Plugin's ZIP file into your components/com_docman directory and that's it!
