Hello,
I am testing Zorin and I love it. I would maybe jump from Linux Mint to Zorin but some basic features do not work like this one :
On all OS (Windows, Mac, other linux), there is a virtual desktop feature with a zidget in the task bar which allows to switch from one virtual desktop to another one.
Would you please strongly consider to add it in Zorin ? It would be very great 
I appreciate your help for improvement
It's already available.
I think I added always displayed button with gnome-tweaks.
Neither Windows nor Most Linux distros come with a Virtual Desktop in the Taskbar (Panel).
I believe you are referring to the Workspace Switcher (wnck-pager) - and this is present in Zorin OS and is default on the panel in Zorin OS Lite.
AGREED, they have got to be talking about the Workspace Switcher.
I never once heard in my life an operating system coming with a virtual machine APP built into the OS itself. The most I've ever heard, is that a VM APP was included in an OS for us.
And even then, most OS's don't come with VM APP at all.
