Google made Docs available for offline editing this past summer and now it's extending the capability to Slides. In a rollout slated to begin today, users of the web-based app (formerly known as presentations for Docs) will be able to edit, comment and control r/w privileges on Drive-hosted slides without being tethered to the internet -- those tweaks will simply auto-upload the next time a connection is established. You'll need to be currently enrolled in offline editing for Docs to take advantage of this new feature, as it's not enabled by default. But if not, don't stress, Google's included detailed instructions in the source below. So, what's next in line for offline editing? Oh, that'd be Google Sheets.
