This is a perfect example of Google's absolute failure at marketing docs/apps.

If this had been rolled out as a feature in Apple Pages, we'd have seen it demonstrated on stage, even if only for a moment, and given an easy to remember name (Pages with "Cloud Complete", Pages with "Net Functions", etc.). There would have been deserved oohs and ahhs. It would have been widely reported on and helped ship units.

Google buries the lede and thus misses another great opportunity to show off a really neat feature.
