One thing I would like to make more like MacOS is the way the display pans when you've zoomed in on it, using the "zoom in" shortcut Cmd-plus. On a Mac, the display pans (moves across the screen) only when the cursor hits the edge of the screen, whereas on eOS it pans continuously as you move the cursor, so you also reach the edge of the display once the cursor hits the edge of the screen. The latter has the unfortunate effect that your display is essentially always moving around, which I find quite distracting (wouldn't anyone?).
If there isn't an Xserver option to get this behavior, please regard changing this as a feature request.
