This is the kwin script version derived from the WorkFlow project. The project is trying to enhance every user's unique workflow by combining existing technologies from Plasma.
cd package
plasmapkg --type kwinscript -i .
You should make a relogin in order for the script to appear in System Settings -> Window Behavior -> KWin Scripts then you check it and apply the changes. You should make a relogin one more time in order for the script to be activated in plasma.
The script uses the global shortcut Meta+Ctrl+Z(which you can change if you want) or you can use the plasmoid WorklFlow KWin Script Launcher to trigger the kwin script
