number of updates to Google Drive today. The update that I'm most excited about is the new option to create slides on the Google Drive Android app. In the next couple of weeks you'll be able to create slides in the Google Drive iPad app too. Along with creating the slides you will be able to share them and collaborate on them as you can when using Google Presentations in your web browser.
Speaking of collaboration, Google Documents now has a feature called "suggested edits." Suggested edits work in a fashion similar to that of commenting on a Google Document. Suggested edits can be made by anyone who has commenting permissions on your document. A suggested edit will be placed in a document but won't become permanent until approved by you. See the Google's animated GIF below for a demonstration of this new function.
