At work, I put the GH editor window on one screen and have a Rhino viewport available on my other screen. When not at work, I only have my laptop screen and am constantly moving the GH editor out of the way or double-clicking the title bar to minimize the editor. What if the editor was transparent and one can see the Rhino viewport behind it?
No problem, it should be optional, of course.
I’ve tried it a bit with the components that @AndersDeleuran pointed to, and while that works fine, I don’t always turn it on. I’m glad to be able to turn it on when I need it but equally glad to be able to turn it off again.
