No nonsense Pop_OS customization, Nemo vs Nautilus
I like Pop_OS a lot, but I personally like to add some modifications.
Nautilus being one of them. It works great, it's fast, it never crashed on me but...
The main - and very simple, maybe even silly reason is the "open in terminal" option in Nautilus opens the default Gnome Terminal.
For the most part this is fine, however I'm (currently?) using Terminator since it's absolutely great for split views and a few other neat things. Like with anything, one must "weigh" effort vs effect, but this is very quick and simple.
To change the default terminal in Nautilus, it used to be possible with the below command, but it doesn't work anymore.
gsettings set org.gnome.desktop.default-applications.terminal exec /usr/bin/terminator
The easy solution for me is Nemo; its essentially Nautilus (The name gives a hint...) but it's modified; and it allows more modifications.
It's easy to install, it doesn't (seem) to mess any ting up and if you don't like it; it's also easy to remove. It also doesn't add convoluted extra system settings, weird extra applications or anything.
sudo apt install nemo
Make Nemo the default File manager:
xdg-mime default nemo.desktop inode/directory application/x-gnome-saved-search
(revert this by: xdg-mime default nautilus.desktop inode/directory application/x-gnome-saved-search)
Now let's make Terminator the default terminal. It's of course no problem to add any other terminal you prefer. Nemo is a cinnamon application so we need:
gsettings set org.cinnamon.desktop.default-applications.terminal exec /usr/bin/terminator
