Google introduces add-on features for Google Docs & Sheets
Announced today, Google is introducing a new layer of features to its Google Docs and Google Sheets productivity web apps. The word processor and spreadsheet editor will now support additional features through user-installed add-ons developed by select partners.
The add-ons are accessible through a menu in the tool bar when editing a document or spreadsheet and include a number of partners like Mail Chimp and Avery. Once prompted from the tool bar, Docs and Sheets will present a store-like interface laying out the various supported add-ons allowing you to install them to your apps.
