Nautilus should be replaced with Nautilus-Typeahead

[Aravisian]

Ah... I do not. I experience the same but the model dialogs being handled do not bother me.
Just different users that go about things in a different way.
Removing Nautilus will break the desktop because it is integrated. It is possible, but I am not willing to walk anyone through it.
But... there is an easier option which is the One I Usually Use on Zorin:

Install Cinnamon Desktop on Zorin:

sudo apt install cinnamon cinnamon-core

Or

sudo apt install cinnamon-desktop-environment

I do not know how you feel about that one. I prefer Cinnamon over Gnome. Others may not agree. But having the full desktop also fully integrates the Nemo Desktop.
And these days, you can get half (Until I make the rest) of the Zorin themes on Cinnamon:

Zenith Cinnamon and Mate Zorin OS Style Themes (XFWM4, too)

A quick reminder of Intent: Zorin OS comes with the Zorin Themes, of which you have Zorin-blue-dark, Zorin-red-dark... and so on. These only fully work on Gnome and XFCE, as those are the desktops that come with Zorin OS. These Zenith themes are complimentary, to add the Additional Support for Mate or Cinnamon Desktops; as Zorin already includes the themes for XFCE and Gnome.
