HIDE PRIVATE INFORMATION IN GOOGLE DOCS - DOCSECRETS

Would you like to be able to hide certain parts of your Google Doc?  You now can by using the Add-On called DocSecrets. Using this Add-On, you can block out parts of text so you only show collaborators what you want them to see. Information like names, email addresses or other personal information will remain private while the rest of the document is shared.

I think this could also be used as an assessment for students.  You could use DocSecrets to hide specific parts of a document and students would have to "fill" in the blanks.  Check out the video by The Gooru for a quick tutorial on how DocSecrets can be used.
