Google has added the task features for Google Docs and Google Slides. Whenever you start a new comment, you can type "+email address" (no spaces) and you will get an option to assign this person a task. ex. +jnorman@cms.edu.do
This sends the person an email to read and complete the task. When it is done, the person can mark it as resolved. A great way to communicate and collaborate.
