Google Drive has just received an update that adds some new features as well as improvements for existing ones. New features include the ability to upload multiple photos and images at once as well as the ability to open and save Quickoffice documents directly to Google Drive.
Other new features included in the update is the addition of Helvetica Neue as a supported font when creating and editing documents. Other features are simply enhancements to existing functionality such as diagonal scrolling and cell formatting when working with spreadsheets. When working with spreadsheets you'll also be able to pinch to zoom on slides. Animation for slideshows have also been tweaked to flow better.
