Redirecting the user to another page for the help might not be ideal as it takes them away from what they're doing. A couple of folks have requested to have the quickstart content available in a Lumino tab so they can have it open whilst working.

There's an issue for this here - #1184 (see #1884 (comment) for clarification), it was also requested recentlyish by our operators to facilitate acclimatation.

Trivial to implement:

We've had another request for documentation (n-window) and a request to advertise the tab layout feature, so opened #2392 (built on this).
