Remaining Tasks

In a somewhat particular order, but not super rigid on that.

Modal (https://phabricator.wikimedia.org/T258209)

• (MC) UI - add footer "View full article history" button
• (TS) UI - Add Thank / View Changes / View Discussion button assets (see https://phabricator.wikimedia.org/T258209#6468770 for assets)
• (TS) Layout - polish all spacing and font sizes (including iPad) (see https://phabricator.wikimedia.org/T258209#6468770 for font sizes)
• (MC) Layout - Try to shrink down the timeline dots & squiggle, it feels too large
• (MC) Layout - if rotate to landscape, scroll down, rotate back to portrait, and scroll all the way up to the top of the VC we the top 100 or 200 points of the VC is hidden behind the underbarheaderview
• (MC) Layout - Fix header issues (seems it doesn't play nice with the iOS13-style pageSheet presentation
• (TS) Layout - Optimize scrolling performance (consider having all side-scrolling cells be the same size to limit sizing layout passes) - they're the same size now, but more performance testing / tweaking can be done.
• (DM) Data - Format edit counts so we have commas (was previously seeing a crash when attempting this, need to look into that).
• Data - Section headers should probably have the == signs stripped.
• (TS) UI - Add theming
• (MC) Other - Tapping snippet links handling/flow
• (MC) Other - Tapping User Name handling/flow (already pops to Safari but we should show in-app web view controller)
• (MC) Other - View changes button handling/flow
• (MC) Other - View discussion button handling/flow
• (MC) UI - "x small changes" needs to be a link (which I assume kicks you out to Page History at those revisions). Also currently if you tap that text it becomes an editable text field, and we need to fix that behavior as well.
