Author's are disqualified from entering :) Yeah the link Scott posted lists the new dynamic presets and direct navigation.
The Project audio folder preset works like a media bin and lists all the wave files in your project.
For project saved with a project audio folder this will list all files in that folder. For global audio projects this will list the contents of the global audio folder. It will even update as you record new wave files in real time.
This can be handy if you deleted something from a version of a project and want to find it (as long as you haven't run clean audio disk). Files from the project audio folder can be dragged in to your project or even to a different project if multiple projects are open.
The direct navigation option is also a handy way to quickly navigate to a folder by typing in its name.
