Scheduled Google Docs Update for July 31st
By the beginning of the school year, you'll be able to edit your Google docs without an internet connection. All you'll need is the latest version of Chrome and the Google Drive app from the Chrome store.
Another nice feature is the ability to preserve previous versions of documents. As you may or may not know, Google deletes any revisions older than 30 days or when there are more than 100 previous versions of the same document. By August, you'll be able to indicate that you want certain versions saved. This could be useful when curriculum mapping.
