Different windows in different Desktops, KDE !

Unlike GNOME, KDE shows all windows on all desktops. There is simple setting to surpass this. Right click on any window on panel( minimized or open) and select Task Manager Settings . From the General option go to Filters and check two options viz. Only show tasks from current screen & Only show tasks from current desktop .

Thats it. Now you can have different windows on different desktops.
