Along with @Gijs , I should mention @pascal as two great examples of helping persons who have made so many truly useful scripts, that, for some reason, remain unused in Rhino. I would love to see many of these scripts being included as native tools in Rhino.
No kidding, the developers at “McNeel” should start a full-time 3d modeling job with Rhino every second day of the week, in order to truly understand the need for better surfacing tools, static Zebra and Light lines analysis, mass calculation, usable rebuild to single-span surfaces (6 control points and degree 5), Gumball with integrated extra handles for “Drag strength”, etc. Only then they will figure out that the current tools in Rhino are underdeveloped and lack major functionalities that could make the workflow much simpler and easier.
Even MOI has a vertical dimension in the Perspective viewport, but Rhino don’t. Hint:
