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.
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.
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.
