set your terminal as the default terminal for Nemo. To do that, you can use the following command: gsettings set org.cinnamon.desktop.default-applications.terminal exec terminal-name. I use Alacrity as my terminal, so
gsettings set org.cinnamon.desktop.default-applications.terminal exec alacritty
Install the Nemo file roller—the file archiver extension for Nemo. Installing this helps extract and compress files.
pacman -S nemo-fileroller
✨ Customisation
To change the theme of Nemo, first install the theme and set it using this command: gsettings set org.gnome.desktop.interface gtk-theme new-theme. I use the catppuccin-mocha theme; it has a nice dark interface.
yay -S catppuccin-gtk-theme-mocha
gsettings set org.gnome.desktop.interface gtk-theme Catppuccin-Mocha-Standard-Blue-Dark
Install lxappearance, then change theme using that to change gtk theme for widgets as well.
You can disable the menubar from the top file options -> View -> Menubar (you have to press Alt to show it after disabling it).
You can customize your toolbar from preferences options, Edit -> Preferences -> Toolbar.
