Why do you assume that you need a plug-in?
Because inherit zoom isn’t one of the options when I go to view and then zoom – unless one of the options means inherit zoom. The options I have are:
Fit width, fit height, fit visible
Pan & zoom
Is fit width, fit height, fit visible the same as inherit zoom?
Have just discovered when looking at properties that Acrobat DC defaults to inherit zoom.
Thanks for your reply though.
