Being able to zoom out the camera and see the entire world is amazing, but I wish there was a mode that allowed you to focus the camera in the center of the world instead of link and made the world perfectly fit in the window size, it shouldn't be much trouble unless the camera is a child of link.
Another thing I would love, but it would be harder to implement is a native way to record your playthrough and replicate it in a similar way to a TAS, but with elements of the BOTW Path of the hero map mode where you can see a trail of your entire journey and things like where you've died and stuff. I'm not expecting it but if you wanna keep adding stuff to this then that would be a cool addition.
