Droogle for Drupal 7 Released Integrating Google Drive and Drupal
Droogle for Drupal 7 was just released and supports Google Drive features and folder level support. http://drupal.org/project/Droogle Droogle is a project I've authored that is sponsored by Babson College, and integrates Google Drive (formerly Google Docs) with Drupal. There is now both a Drupal 6 and a Drupal 7 version available. Folders are now displayed -- out of the box the css supports up to 5 levels of folders, the php supports infinite levels, and the css could easily extend to support more levels.
