Google have updated their Google Docs app, with great new features such as a better reading interface on tablets and an offline mode.
The offline mode allows files to be saved on to the device when there isn’t any internet available. This makes these files available at any time. Google Docs also updates these files that have been updated when the device is in offline mode, but only when the device is connected to WiFi.
The interface when reading a file has also been updated. A high resolution version of the document is provided, and switching page can be done by either swiping left to right or by using the slider.
