- 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.

=== Open questions

What do people who have the `Enable quick topic adding` **disabled** to 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.
