Ever want to edit Google Docs or Slides (Presentation) without a connection? You can enable offline mode in Google Drive. This allows you to edit Docs and Slides and view Spreadsheets. You changes get synced when you get your connection back. Handy when on a train with a Chromebook and the 3G is a bit dodgy. Screen shot of how to enable: Just click on more in your drive (under Recent) and click on Offline Drive and enable it. Job done.
