Yeah, it likely won’t support that any time soon, because it’s incompatible with Extended Window Manager Hints standard.
Having said that, Plasma 6.6 (which just came out) allows for having only a single virtual desktop on non-primary monitors, which is all I wanted, personally…



















Did you try on KDE since Plasma 6 came out? It introduced a native, manual tiling mechanism, which just needs to be configured by a KWinscript to make it automatic, so it still feels native when you resize the tiles. I’m pretty happy with Krohnkite these days either way…
