This may be the coolest Google trick to date! Doctopus runs a script in Google Drive to automate the creation of docs, hangouts, and more, plus creates a grading platform.
This free app works with Gmail (and school Google Apps email accounts) to link attachments to cloud storage. Could be another piece to the workflow puzzle.
Though $7.99 seems steep for an app, not only does this one allow you to edit Office documents (same as Pages, Keynote, & Numbers), but it also lets you work on Google Docs.
