I didn't install any spins, just the Plasma desktop packages and the few KDE apps I use. GNOME still works, but I rarely log into it.
Having it side by side on the installer would be the right way to do it!!!
openSUSE guys also do it that way (no advanced button, however! just an extra step at the installer)
The Fedora KDE Plasma Desktop Edition is a powerful Fedora-based operating system utilizing the KDE Plasma Desktop as the main user interface.
The change means moving it into the "Editions" label!!!
(hopefully label it as Plasma Workstation vs Gnome Workstation)
