you cannot use it via bash you configure it and it applies actions to windows as they are created you cannot use it at all where plasma isn’t your desktop and as of wayland you cannot use a different window maanager with KDE plasma as wayland doesn’t have the idea of window managers.
I don’t think you are ever again going to have an agnostic way to do this




I meant there is no particular reason to expect a gui configuration tool for a gui Window manager that isn’t expected to be dynamic to have a cli.
Generally the use case is always maximize this window or always put it on a particular workspace etc.
If it has any path to being addressable via bash you would check its dbus interface if any.
The same feature on say i3wm also isn’t a CLI nor is it any more dynamic.
Windows rules and wmctrl don’t have identical use cases although there could be overlap
