If you find the latest version of Nautilus now called Files of Gnome a bit lacking in features, you are not alone. Enter Nemo, a fork of Nautilus by the Linux Mint guys. It knows a few tricks that Nautilus forgot but a power user could really appreciate, like 2-panel navigation.
To install Nemo, open up your terminal and type:
sudo apt-get install nemo
Yes, it’s that simple, Nemo is in the default repositories for some time.
To set Nemo as the default file manager instead of Files, you need to enter one more command:
xdg-mime default nemo.desktop inode/directory application/x-gnome-saved-search
