Leaving aside creating a pano, I normally use my Nikon D850 in max resolution to create my RAW images. With the size of my base layer in mind, like Photoshop, On1 creates its layer stack based on the background layer. When using Photoshop, whenever I can, I flatten the image in order to control the image size being editted. I suggest a Flatten Image function be added to On1.
