Google Updates Gmail Offline Chrome App

Last August, offline Gmail returned to Google Chrome after a brief absence, during which it went from being a Gears-based feature to an HTML5-powered Chrome Web Store app. Now Google has updated that app. Hit the jump for more.

The updated Google offline Chrome app now lets you exercise a fair amount of control over the amount of mail that can  be accessed offline. You can now choose “whether you want to synchronize 7, 14 or 31 days worth of mail.”  Previously, only 7 days’ worth of email was available offline. But that’s not all. The updated app includes a few other improvements:

• Improved attachments: All attachments are now downloaded and available for offline use
• Keyboard shortcuts support: If you have keyboard shortcuts enabled in Gmail, your setting will transfer over to the Gmail offline app. If you're not sure what you can do with keyboard shortcuts, try pressing ‘?’ next time you’re using Gmail or Gmail offline.
• Numerous performance enhancements: Messages and attachments now download at a faster rate and some bugs have been fixed.
