G Suite allows users to track who viewed a document on the new activity dashboard, as well as the time and date it was viewed. This useful feature in Google Slides, Docs, and Sheets allows users to see every comment and suggested changes made in a file.

Last March 2018, Google updated G Suite by adding a new activity dashboard to Slides, Docs, and Sheets. It allows you to see the accounts that viewed a certain document and when they opened it, allowing you track individual contributions to a group project.
