This would be very useful for my use case as well.
I designed a large scale mobile app for iPhone with iPhone size artboards. My client wants to meet on zoom and review. I open a preview of my mockup in Xd and there are huge black borders around the app making it too small and blurry on my client desktop monitor.
This would fix a second use case of presenting on a large format display, like a meeting room TV. The mockup previews do not scale up when connected over HDMI or casting.
Agreed with the original poster about adding 200%, 300%, reset to 100%. I would also add "Fit to preview window" so that whatever size you make the preview window, the app will scale. Scaling up to fill the screen may result in loss of pixel quality for tiny artboards using raster graphics, but I think the tradeoffs in viewability and usability are worth it.
