Google Docs for Android has always been a decent stand-in when you need to edit on mobile, but it's hardly the full experience. For example, even changing the name of the file you're editing has been buried. Now, that changes with the app finally allowing you to edit a file's name in the slide-out option menu.
The new updates to the Docs suite also brings a few other useful features. Most notably, it's now easier to track changes when you're working on a Microsoft Office file type (Google Docs files still do this automatically). The updates are rolling out now, or you can skip the line and download them from APK Mirror.
