The linux Mint team forked Nautilus, the filebrowser from Gnome. They added a lot of new functionalities so it's worth while to give it a try. In all ubuntu based distros you can do that by adding a ppa:
sudo add-apt-repository ppa:gwendal-lebihan-dev/cinnamon-stable
sudo apt-get update
sudo apt-get install nemo
What 's interesting about Nemo:
* All the features Nautilus 3.4 had and which are missing in Nautilus 3.6 (all desktop icons, compact view, etc..)
* Open in terminal (this is part of Nemo itself)
* Full navigation options (back, forward, up, refresh)
* File operations progress information (when you copy/move files you can see the percentage and info about the operation on the window title and so also in your window list)
* Proper GTK bookmarks management
* Open as root (this is also part of Nemo)* Ability to toggle between the path entry and the path breadcrumb widgets
In version 3.6 some things have evolved:
The Linux Mint / Nemo developers have also ported some Nautilus extensions to Nemo: there's a Dropbox extension for Nemo, along with Pastebin, Seahorse, Fileroller and Samba extensions.
What's not interesting about Nemo is some lack of integration in the OS. No visible connection with Ubuntu-one or Dropbox., In version 3.6 it's better than in version 3.4.
