Google took to the Official Gmail Blog today to discuss some updates it has made to the Gmail offline Chrome app.

First would be the addition of a settings page, which lets you choose if you want to sync 7, 14 or 31 days worth of email. “So the next time you get on an airplane, you can sit back and tackle up to 31 days of mail all while offline,” says senior software engineer Dave Stewart.

With the app, attachments are now downloaded and available for offline use. This should be incredibly helpful for those wanting to actually view the content of their email.

Messages and attachments download at a faster rate, Google says.

There are also some bug fixes and keyboard shortcut support has been added.

“If you have keyboard shortcuts enabled in Gmail, your setting will transfer over to the Gmail offline app,” says Stewart. “If you’re not sure what you can do with keyboard shortcuts, try pressing ‘?’ next time you’re using Gmail or Gmail offline.”

Google says the improvements will be there the next time you open the app.
