POD_GH_BUTTON is the add-on that adds that floating RhinoViewport and split view.
I want to do something similar, but am unable to figured out how to add a interactive viewport to eto form.
I’ve found that if I just call ViewportControl vpc = new(); I get the viewport on the right, which is interactive, but if I put vpc in a eto form, it becomes non-interative (left), and it doesn’t redrew/refresh automatically
