Tip: Gmail Offline

On the train or on a plane, if you find yourself without an Internet connection, you can still manage your inbox by enabling Gmail Offline.

• Just go to Gear, Settings, Offline.
• Click "Install Gmail Offline".
• When the Web store opens, click Launch App. 
• Once installed, choose "Allow offline mail".

Now, you can set the amount of email you want synced: 1 week, 2 weeks or 1 month. Read email or compose email offline! When you get back online, your mail will be sent, and a new sync will occur.
