Quick update for Ubuntu users who have upgraded to Ubuntu 14.10 or are planning to do so in the near future: today I updated the WebUpd8 Nemo PPA with packages for Ubuntu 14.10 Utopic Unicorn.
Ubuntu 14.10 already has Nemo 2.2.0 in its repositories however, that package is built for the Cinnamon desktop and it doesn't work properly in other desktop environments (for instance, it doesn't draw the desktop).
On the other hand, the Nemo package (version 2.2.4 at the time I'm writing this article) available in the WebUpd8 Nemo PPA comes with various patches which make Nemo work properly under Unity (and not only: even though the package is built with Unity in mind, it should also work with Xfce, GNOME Shell, GNOME Flashback, etc.). Also, the WebUpd8 Nemo PPA contains the latest version for all Nemo extensions, backported from Linux Mint.
For more information about Nemo (with Unity patches) from the WebUpd8 Nemo PPA and installation instructions, see the following article: Install Nemo With Unity Patches (And Without Cinnamon Dependencies) In Ubuntu
I'm in the process of updating all the WebUpd8 PPAs for Ubuntu 14.10 Utopic Unicorn, so if you're using Utopic already, expect to receive quite a few updates from the WebUpd8 PPAs today.
