Easily access virtual machines via Unity VM lens

VirtualBox is a handy powerful utility, that allows the user to install operating systems inside one's actual production machine, thus the user is able to test, run, learn about, access specific apps from various OSes, etc.

After an OS is installed as a virtual machine, searching a specific virtual machine is to be performed by opening VirtualBox and locating the searched item, actions followed by further clicks (necessary to open the actual OS).

Unity VM lens is a useful lens, housing virtual machines created via VirtualBox in the "warmth" of the Dash.

Basically, adding a new OS to VirtualBox, automatically pushes the added OS into the VM lens, featuring a specific icon and title, latter addition useful to properly identify the about-to-be-accessed virtual machine.

A definitely interesting aspect of Unity VM lens is its VM maneuvering, meaning, the lens, along with gathering and exposing VMs, allows the user to directly open the clicked VM (clicking on a VM, directly opens it via VirtualBox, without intermediate steps, such as launching VirtualBox, and then the user opens a VM by cliking on it).
