New functionality from third-party organizations
Google has today announced the arrival of add-ons for Google Drive, bringing new capabilities from partner developers to its web-based productivity apps. Activated from the new "Add-ons" menu when editing a document or spreadsheet, add-ons are available from a variety of developers and accessible throughout all your Google Docs or Sheets once you've plugged them in. There are already a few dozen add-ons available, including Merge by Mailchimp, Avery Label Merge and EasyBib bibliography creator, as well as a selection from Google itself, and the company says more are coming in the future.
Right now you'll need to use the web interface to get the most out of Google Drive add-ons, as the add-on menu isn't available in the Android app. Nevertheless, add-ons could allow Google to further close the feature gap between Drive and desktop-based office apps, such as Microsoft Office, with optional extras like easy label printing, table-of-contents generation and builtin translation.
To try out Google Drive add-ons, load any document or spreadsheet and take a look at the "Add-ons" menu.
