This is where the interesting stuff happens!
Depending on the timeline you will see different statuses, but each status has a standard structure:
-- Profile pic, name and link to profile. An optional left-arrow if it's a reply to another status (hovering will reveal the replied-to status). Clicking on the profile pic will uncollapse the user's profile.

- A `+` button on the right allows you to Expand/Collapse an entire discussion thread. It also updates in realtime!
- An arrow icon allows you to open the status on the instance where it's originating from.
- The text of the status, including mentions and attachements. If you click on a mention, it will automatically open the profile page of that person.
