Ok, I’ve fiddled with the idea a bit, and it should be working now. You may need to do a hard refresh of the page to trigger things (or just wait until you sign in again). These links should show up in the header now:
If you scroll down, they will scroll away. If you scroll back to the top, they will be there again.
Also, it should work for everything from an iPad (768px wide) and up. Anything smaller will not see it (just use the links in the hamburger menu at that point).
