OK, how do I open an app (GKrellm) on multiple desktops? I used to used kstart --alldesktops and that worked great, until I upgraded KDE and it didn't - seems kstart5 was its replacement. Which didn't work, telling me "invalid application" or somesuch. So I switched to defining Window Rules. Which worked, until I upgrade to Fedora 34 this morning, and that stopped working.
So what's the magic incantation to get 4 GKrellM panels opening on all of my 3 virtual desktops?
