But luckily most of these "dropped" features are actually additional features that Nautilus offers via its plug-in API thus using or installing the appropriate plug-in we can easily get those "missing" features nonetheless.
In that sense, as said some GNU/Linux distros do include it but concerning recent versions of Ubuntu Linux... there is a certain (rather very useful as well) feature that basically lets you open the Gnome Terminal emulation window in any folder as easily as right-clicking on the folder. This how ever is not installed by default in the Nautilus version that comes in the Ubuntu OS.
This is a very useful feature to have because let's say that you downloaded a .deb archive package to a certain location in your HDD and to install it you had to change to that directory in the Terminal window... then sometimes (especially if the folder name contains a lot of numbers/versions, different types of characters, etc which is boring and hard to type and time consuming, etc) having installed this plug-in makes doing things much more easier!.
It's called "Nautilus Open Terminal". Since Ubuntu has this as a pre-build package in their repositories, you can easily install nautilus open terminal plug-in in Ubuntu 11.04 Natty Narwhal, 10.10 and 10.04 (may also work in other older versions) by using the below command.
sudo apt-get install nautilus-open-terminal
To apply it system wide you'll have to restart Nautilus. To do that, again open your GNU/Linux terminal and enter the below command.
After than you can open the Gnome Terminal emulation window in Ubuntu in any given folder (should also work in Unity) as easy as right clicking and choosing "Open in Terminal" which is very handy as mentioned before. Enjoy!.
