**Research questions:**
1. Does positioning all mobile context items at the bottom of the screen and making them larger cause contributors to engage with them more often?
-- Read: do contributors tap edit “✎” more often?
2. Do "Edit cards" cause more contributors to engage with adding/modifying links and citations?
-- Asked another way: "What percentage of contributors who are shown the edit card (revised) or context item (existing) end up engaging with it?" How deep do contributors go into the workflows of adding/modifying links and citations?
3. Do "Edit cards" increase the percentage of people who successfully add/modify links and citations?
4. Do “Edit cards” and the revisions to their subsequent workflows cause a higher percentage of contributors to have success adding/modifying links and citations?
-- What % of contributors who start to add/modify a link and citation are successful in doing so? How do these proportions compare across the existing and revised workflows?
5. Do "Edit cards" cause contributors to engage with adding/modifying links more frequently?
6. Do “Edit cards” cause more people to save their edits (read: edit completion rate)?
-- What % of edit sessions, in which contributors successfully add/modify a link, result in them attempting to save their edits?" How do the revised and end existing flows compare in this way?
