An update for Google Docs is currently rolling out through Google Play, enabling users to focus more on reviewing documents before jumping in and editing them.
To be more clear, as you scroll through an opened document, editing icons will vanish to the top, allowing you to focus more on what is in front of you. If you need to edit something, simply double tap the screen, or press the blue pencil action button.
The update just hit my device, so you can sleep well tonight knowing it should hit your device soon if it has not already.
Go grab it.
