Google is furthering the offline capabilities of Gmail today with the introduction of attachments support. According to the company, these was one of the most requested features for Offline Gmail and starting today, users will be able to attach files in offline mode the same way they would in online Gmail.
The added functionality is not groundbreaking by itself, but it was a necessary step towards making Gmail as robust as desktop based alternatives such as Microsoft Outlook. To use this feature, you'll need to either use Google Chrome or download the Gears add-on for Firefox/IE6+, and then enable Offline Gmail from the Labs tab under settings. You'll see the "Offline" link on the top right corner of the Gmail page after reloading it.
