KDE has very basic FancyZone inspired functionality that is very sub par (doesn’t let you have different layouts on different virtual desktops for example). There’s a KDE addon (I think) called Polonium that is a bit more capable I think but I haven’t tried it. Other than that there’s the desktop environment COSMIC that’s in the works that’s supposed to be a very tile/zone friendly regular desktop environment.
Ah, the John Cleesachu.
