I would like to see an improvement in thee current view range setting. As you can see below instead of the help style picture on the left ii would propose you can generate a section view from your project where you can adjust the grips to change the view range in your floor plan or Ceiling plan on the fly.
It can be quite tedious and laborious to find a perfect height or a right level to set your ranges to, having a live update on screen would be so much more helpful and time saving.
