Better touchpad support

[ArtDoctor]

Is your feature request related to a problem? Please describe.
Yes, the feature is related to the touchpad's scrolling behavior. It's extremely fast, a lot faster than mouse wheel. A tiny movement causes the page to scroll significantly.
Also, the scrolling happens in jumps, not smoothly. For example, there's no movement when I start to scroll, but if I continue, it suddenly moves past a large section of the page. I believe it should start moving immediately and at a more moderate pace. I'm not sure if this is an issue with my laptop or a common problem.

Describe the solution you'd like
I would like the touchpad's scrolling sensitivity to be adjustable. It would also be cool if the scrolling could be made continuous, with smooth scrolling. For example like in basic PDF viewers in browser.

Describe alternatives you've considered
So far I had to use the mouse instead of touchpad for better experience.

Additional context
I have attached a video of how it behaves on my laptop, and included default PDF viewer in OperaGX for comparison.

Thanks for reporting this. I'm aware of the issue but sadly wasn't able to find a quick fix since it seems to be an issue with the UI library we are using. It is on the top of our todo-list and we'll definitely look into finding a solution for this very soon.
