google docs with offline access for android phone

Google provided an update for the google doc app for android mobile phone users. Updated it yesterday for my samsung galaxy ace.
Now just select any file in Google Docs to make it available offline. Google Docs automatically updates these offline files when Wi-Fi is available. One can also manually update files anytime with a data connection by opening the file or tapping ‘Update’ from the Offline section of the app.
