all right, i've installed the latest solaris 11.4 CBE version in virtualbox! i installed the solaris-desktop, openCSW, virtualbox guest additions, and some other stuff. here's my desktop at the moment, let me know if there's anything you think i should try. GNOME is on version 45 which is much better than the ancient GNOME 3 the previous build had, and firefox is on 128.8esr which is actually usable!
