Discourse just rolled out a new “Custom header links” feature. If you refresh your Forum page, you should see this if you’re on a desktop, on the right-hand side:
minor thing, but when you view the Forum in desktop mode and make the width of your browser window small, the iNatForum logo shrinks down and looks weird. (it looks fine in mobile mode.) not sure you can do anything about that.
does it appear for you when you’re scrolled all the way to the top; the instant I slightly scroll down from the very top of the page, it disappears for me. But it reappears when I scroll back to the top
You’ve refreshed the forum tab in your browser? Maybe try a hard refresh of the page?
I’m not famliar with the extension. Is it made by Discourse? If not, then there’s no reason to think that the extension creator supports this new functionality.
