I suggest adding an option that would adjust the sensitivity of the "zoom cursor" according to how zoomed in it is. Higher zoom = lower sensitivity.

Isn't this relative sensitivity?

Like a screen magnifier like Ok Boomer?

No, it is about the smoothness of the scrolling on normal zoom.

What do you mean by zoom cursor?

The area displayed on screen as zoomed.

I guess it is, but it's far from "accurate" relative zoom, just compare ok (z/b)oomer straight with zoomify and you'll understand what am I talking about

Relative sensitivity is this. The higher the FOV divisor, the lower the sensitivity, the strength of this is configurable with a slider.
