Google Docs may be known as the "lightweight" word processor, but that doesn't mean it's lacking in advanced productivity features.

Two such examples I myself forgot about up til recently and then was delighted to rediscover:
1. Explore: Intelligent in-document multitasking
Ever find yourself editing a document on your phone and needing to get more info about a particular subject? Docs' Explore is just the thing you want.
