Description Nicolas Dietrich 2020-05-13 21:54:31 UTC 
Some tools (e.g. gimp or web maps) set the center of the zoom operation to the mouse pointer when the zoom is triggered by a (ctrl+) mouse-scroll. This is very convenient as it allows you to make sure to keep something in view when zooming in.

Okular currently doesn't do this, but always zooms into/out of the center of the current view (which is fine for ctrl-+ / ctrl--).

It'd be great if this could be implemented - thanks for considering :)


(Evince seems to do this, this is the corresponding bug report: https://gitlab.gnome.org/GNOME/evince/-/issues/11)

Yes, this is what I want, great! (though I haven't tried / built it)
