Oh yeah browsers are really just another service (and that's what we try to treat it as, as well!) and it's really the same set of questions you'd ask of any service, but for some reason the tooling completely stops either at the frontend or at the backend.
As for monospace font - feedback received! Is there a particular section you think is too overwhelming? (search page, nav bar, etc.) We've been thinking of how can we balance between the ease of monospace for reading instead of having it literally the default on every UI surface :P
