This task involves the work with of introducing the {nav Add topic} button with the version of the site-wide sticky header that will appear on pages volunteers use to host discussions.
=== Requirements
**Meta**
- The "Add topic" button should appear within the Sticky Header on any page where the {nav Add topic} / {nav New section} link //already// appears within the page chrome.
- Platform(s): **desktop**
**User experience**
- Regardless of the state of peoples' `Enable quick topic adding` setting in `Special:Preferences#mw-prefsection-editing`:
-- People should see a button within the sticky header that, when clicked, will open //either// the legacy `section=new` experience or the New Topic Tool.
-- This text that appears within this button should match the text a wiki has defined for the existing `Add topic` / `New section` link that appear's within the page's chrome.
- For people who have the `Enable quick topic adding` setting **enabled**:
-- When they click the {nav Add topic} / {nav New section} button, the New Topic Tool should open
- For people who have the `Enable quick topic adding` setting **disabled**:
-- When they click the {nav Add topic} / {nav New section} button, the legacy `section=new` experience should open
=== Open questions
[x] 1. What do people who have the `Enable quick topic adding` setting **disabled** see within the version of the sticky header that appears on talk pages? //Note: the current spec would make it so the {nav Add topic} button continues to appear within the sticky header. Once clicked, people would be taken to the legacy `section=new` form.//
-- People who have the `Enable quick topic adding` setting **disabled** will see the {nav Add topic} button appear within the sticky header. Once clicked, people will be taken to the legacy `section=new` form.
- [ ] 2- [x] 2. How will the {nav Add topic} button that will appear within the sticky header be styled? //See current button styling in the `Mockup` section below.//
-- The {nav Add Topic} button will appear as a quiet button, per what @alexhollender_WMF and @KieranMcCann converged on in T304187#8025546
