When I say "gradual zoom", I am referring to how the mod "Ok Zoomer" zooms in, instead of how logical zoom just snaps straight to being zoomed in, it would be better if it had some sort of zoom over a small period of time to make it look more aesthetically pleasing.
The reason why this would tie in well with Mod Menu support would be so it can be togglable for people that prefer it to be closer to optifine zoom.
