Myself and a colleague were discussing how useful it would be for Zbrush to have a floating panel where you could see your sculpt from a set view, eg 3/4’s, while you sculpt it from all angles in the main window. We find the secondary window feature in Photoshop to be really useful for being able to “zoom out” and check silhouette really fluidly while you work. It would
probably be really great for screen capture/streaming purposes too.
