The Explore tool in G Suite (formerly Google Apps for Education)

At the end of September, Google Apps for Education underwent a change of name to become G Suite for Education. This was mostly a marketing change but there's one notable addition and subtraction in Google Docs, Slides and Sheets. In the lower right corner of any Doc, Slides or Sheet document you'll see the Explore icon (you can also get to there in Docs and Slides through the Tools menu).

Explore opens a sidebar with Google search capability, which allows you to search the web, find and add images, and search your own Drive without leaving the document. In Slides and Sheets, the Explore tool will also make recommendations on design or formatting based on content. In Sheets, you can even use the tool to create formulas and charts or other data visualization.

Unfortunately, the addition of Explore is tempered by the loss of the Research Tool, which had similar functionality in Google Docs but also included the ability to add citations and footnotes directly into a doc. Since it's early days yet, the citation tool may be revived in the future.
