I would like to have a choice about whether the PhotoView preview window opens when all you want to do is make the final rendering. If the preview window is closed and you select "Final Render", the preview window pops up and hast to start rendering before the Render window opens and starts the fianl render. this to me seems like a waste of processor time. Sure I can hit the Pause button on the preview window, but I have to wait till that button becomes active. When the final render is done the preview window comes out of pause and starts rendering again, which takes up processor power better used to deal with saving the image just created. I don't see the logic of this.
