should allow zoom out
The render preview window should allow you to zoom out!
Hi! The render preview window corresponds to the view on your current 3D viewer. So zooming in and out on the canvas will reflect on the preview window. Is there a specific reason you want to only zoom out on the preview window? Would love to know more about it!

Like in cinema 4d when it is rendering to an image file , it allows you to view the render at different scales as it's progressing so that you can see different parts of it in different ways so as to get a better idea of how it will look since render time is important and I don't want to waste any if one part of my image is not correct.
