Hi,
I'm using a laptop touchpad and using the "Scroll Image" option for the Viewer/Standalone Viewer/Mouse Buttons/Mouse Wheel setting.
I want to be able to scroll across the image with the touchpad and use Ctrl+scroll with the touchpad to zoom.
Ctrl+scroll does have the zoom function already, although I couldn't find where to customize it (It's not in the Keys list?).
However, the zoom steps are huge (unusably so on a laptop) and the scrolling/panning also happens in huge steps when using the touchpad in two-finger mode with the "Mouse Wheel" setting mentioned above. I would like to ask if there's a way to zoom and scroll smoothly via the virtual "scroll wheel" of a touchpad, in a similar way to how scrolling on a website on a laptop happens smoothly, i.e. not in steps.
As a working example, Windows 11 "Photos" viewer does allow smooth zooming with the touchpad, although there is no option to smooth pan with two finger touch there either, and panning is smoother in the dopus image viewer anyway (only when panning using the left button, not the "scroll wheel"). Perhaps a better working example of what I want to achieve is MS Paint's behaviour, where Ctrl+Scroll allows smooth zooming and Scroll allows smooth panning.
