How do students save their writing as they work?

Students' writing is saved automatically as they write, so they don't need to do anything in particular to save their work. 

If students are writing in the app and not an embedded Google Doc, they'll see grey text, just above the text box.

This text will indicate when writing is being saved and when all changes have been saved. If students are writing in a Google Doc, the doc functions as it normally would and writing is also saved as the student works.
