“Nautilus is the default file browser in Ubuntu and
Nautilus Elementary is a patched version of Nautilus with an
emphasis for simplicity. The whole idea originated during the 100
paper cuts for Ubuntu Karmic and it was stated that the menu and
columns are too big and take away precious real estate. But the
idea never took off and in its place came Nautilus Elementary.“What are the new stuff Nautilus Elementary brings to the
table?* A much simplified and good looking nautilus which can give
KDE’s Dolphin file browser a good run for its money.
* Integrates well with almost all kinds of themes.
* Breadcrumbs are awesome.”
