1) Flight visibility conditions should be impacted by the weather. Heavy fog, rain, snow, etc should make look/peer barely usable at times. Forcing a skilled pilot to fly solely off of instruments.
2) Landmarks should be added to Withmore much like the Badlands. Where you can see things like NLM Tower, the Hall of Justice, etc as you fly closer to them. Landmarks should be more prevalent in topside sectors and difficult to find downside due to sprawl and mixers purposefully meddling with signage to make it more difficult for corps and the WJF to navigate.
