Google has renamed the apps in their Google Drive platform.
Documents is now named Google Docs. Spreadsheets is now called Sheets. Presentations is now called Slides.
All of these services now get their individual apps on the Chrome Web Store. Google would also load them as default apps on their Chrome OS based devices.
The company said:
Starting today, Documents, Spreadsheets, and Presentations - now called Docs, Sheets, and Slides - are available as apps in the Chrome Web Store. Once you’ve installed them, you’ll have shortcuts to these apps every time you open a new tab in Chrome. In a few weeks, Chromebook users will see Docs, Sheets, and Slides in your apps list by default, too.
