How do you do?
Immediately after boot I got to the GhostBSD desktop with standard GNOME layout: panel with menu and notification area on the top and panel with taskbar at the bottom.
Desktop itself is in green colours. If you don't like it (and I don't), you can choose from a dozen of other wallpapers. Those with space theme are definitely enjoyable!
There are 4 virtual desktops by default with switch panel in the bottom right corner.
In other words, once booted, you get into pretty standard GNOME environment. Nothing here tells you you're in BSD. Adventures start when you start acting.
