|This is how it looks like :)|
So as a result the Nautilus elementary project was frozen ... I mean kinda, but the good news is that few days ago the developer claimed that after seeing the enthusiasm from the "crowd" even after it was frozen for a while, it gave him a bit of a boost to re-start the whole project. So as a result if you use Ubuntu 11.04 alpha version or Natty then you can actually install the Nautilus elementary's latest version via the PPA easily.
So if you want to install it , open your terminal and issue the following command...
sudo add-apt-repository ppa:am-monkeyd/nautilus-elementary-ppa
sudo apt-get update
sudo apt-get upgrade
Also don't forget to restart your Nautilus file manager, to do that copy and paste the below command...
*. Note - Remember, by upgrading to this version won't bring any new features unfortunately, but still it does brings some bug fixes nonetheless.
