Is it possible in KDE to set up keyboard shortcuts similar to what Unity uses for window placement - i.e. Alt - Ctrl - Numpad 6 to make a window occupy the left half of the screen etc.?
The KDE global keyboard shortcuts: System Settings > Shortcuts and Gestures > Global Keyboard Shortcuts. Pick the KWIN as the KDE component. You could set the keyboard shortcuts to the window position/tiling etc...
