Suggestion: Extra Traffic Light
There are currently three indicators (I actually prefer the thumb) for OK, broken and Pass_L. Now, we know the system can detect whether the navbar is HTML or SSNB ... so how about a new, blue, light for HTML navbar? (at least on the managing side). If this is thought confusing for visitors, it could appear green to the public. (But if yellow Pass_L isn't an issue, I doubt it would be a problem).
