==== Pitch
Users can scrub a timeline to view article changes and meta information (editing history spark line); when you scrub to current time it live updates
====User story
As a user of the iOS app, I would like to see how an article has changed over time without being overwhelmed by too much granular information.
-----
====Proposed Design
While the goal will still be to have a visual approach to this experiment, one initial thought is to define what the important moments in article development are and to leverage those in the article view for a subset of popular (trending) or currently evolving articles.
=====Design details
For articles that are 'trending (eg. top read)' or 'in the news' consider additional treatments on the article view:
- Highlight the time the article was last updated with specific call outs for 'significant' updates
- Below the article infobox and/or first paragraph, add an interstitial card that highlights the last two 'significant' updates made to the article.
- Tapping on an update to an article section would scroll to the updated text in the article
- Tapping on an update to the talk page would open the talk page or an iOS specific presentation of the discussion (to be designed)
- Tapping on read more would open a view where the user can browse significant updates to the article (to be designed)
- Tapping on the username associated with an update would open the user's talk page in the app
