So, at the moment zoom shortcut (Z) just zooms in the middle of the image.
At the same time command + click shortcut in preview zooms image to the point of click.
After this step this zoom spot is applied to every image for Z button shortcut and you need to manually click to the middle with command + click to kind of reset it to default.
I think we need options here.
I think it would be great if
1. Z button shortcut always zoomed in the middle of the image
2. Z button shortcut with mouse pointer hovering the image zooms to where the pointer is (taking over command + click feature) but only once, not memorising the spot
3. Command + click could be kept as permanent zoom area setting
4. Zoom scroll with mouse wheel should definitely work as p.2 and not just zoom to center
5. There should be a reset button for zoom spot
