Enable VPN connections with Unity VPN lens

VPN (virtual private network) is a handy technology, that allows users to connect computers to remote computer networks via a secure connection, resulting in numerous use cases, such as the ability to access numerous resources (printers, databases, files, etc) on remote networks.

In order to add a VPN connection, navigate to Unity panel's Network Indicator-->Edit Connections-->VPN-->Add, followed by entering the required connection details.

Unity VPN lens is a useful lens, that gathers and displays one's VPN connections in the handiness of the Dash.

Opening the VPN lens, automatically exposes the available VPN connections with fancy monochrome icons and connection titles, latter detail useful to properly identify the about-to-be-accessed VPN connections.

Its usage is as simple as typing a word in the search area and clicking a preferred displayed item, action that enables the clicked connection via a double-sided approach: if (when creating the connection) the password is not entered (and Connect automatically is not checked), clicking on a non-previously-entered-password connection, summons its Network Connections' dialog (requiring a password to be typed), if all the needed-for-a-VPN-connection details are already typed, clicking on a Unity VPN lens' exposed item, directly enables the VPN connection (no intermediary dialog).

How do we install Unity VPN lens 0.2?
Add the following PPA (Precise)

sudo add-apt-repository ppa:themiwi/unity-lens-vpn

then, restart the computer.

Worth mentioning
Adding a new VPN connection, is automatically added to the lens, without restarting the computer.
