Google is updating its Google Drive platform to allow developers to offer add-ons for Docs & Sheets. Meanwhile the company is also updating its Chrome Web Store policies, allowing, (among other things), for developers of browser extensions to charge for their tools.
You can access add-ons for Doc & Sheets through a new add-ons menu in the web apps. For instance, there are add-ons for translating, creating a tablet of contents, importing names and addresses from a Sheet to a Doc, and more.
As for the changes to the Chrome Store, developers can now offer free trials for Chrome Packaged apps and sell browser themes. Google had already let developers charge for hosted apps and offer subscriptions and free trials. Now a free trial option is also available for Packaged apps, which allow users to download data to their device so that apps can run like native software.
The biggest change comes in the browser extension space, where for the first time developers can offer paid extensions, charge subscriptions, and offer free trials.
Developers who want to charge for extensions or packaged apps can use Google’s manager in-app payment service.
