Dropbox Paper's DIY new feature announcement

Showing users your product's new feature is one thing, but having them use it is another. Dropbox's Paper product, a collaborative document editor for teams, does just that through its beautifully designed feature-adoption process. Check it out:

On the bottom of the screen, a large colored banner explains various features through a series of animated instructions. These instructions show new users how to change titles, insert images and tables, and change text formatting within Dropbox Paper. We like this style of onboarding because it naturally engages users, and offers immediate positive feedback.
