Nemo is a fork of GNOME Files / Nautilus. It is also the default file manager of the Cinnamon desktop. Nemo is based on the Files 3.4 code. It was created as a response to the changes in Files 3.6 which saw features such as type ahead find and split pane view removed. Because Nemo was forked from Nautilus 3.4 it includes features removed from Nautilus, like dual panels (split view), list view, configurable toolbar, as well as type-ahead find.
Ctrl-L will toggle between ‘breadcrumbs’ path bar, and location entry, which will show you the current path. Nemo is simple to configure graphically but not all options are in the preferences screen in Nemo. More options are available in the dconf-editor under org.nemo.
sudo apt install nemo
review: Nemo Sidebar customize limitations. Shows "home" directory as if it were the root tree of a file system much like nasty Micro$oft does, stop trying to dumb users down. On the positive side it supports bookmarks and loads quickly. It is well integrated into the Cinnamon desktop for obvious reasons. Mint users should not remove Nemo as it has some useful options relating to GVfs.
