That's the idea behind declarative QML scripting: a very powerful user interface to replace effects. With declarative KWin scripts you get the complete power of KWin exposed + QML + anything you want to import from QML (e.g. dataengines). > (for example the plasmoid currently uses atoms from Xlib in order to move > a task from activity to activity, I dont think scripting can do this > right now) Right now not, but if you mention that to me, I can add the bindings in less than five minutes and with KWin scripting it does not need XAtoms.
