Edge snapping allows to tile a window to the right half of the screen when the right screen border is touched while dragging a window (same for the left border), while touching the top border will maximize the window. 

When the orientation of the screen is vertical, this behavior doesn't make sense anymore. Indeed tiling a window to the right half of the screen will make it narrow and long. It would be great if KScreen can automatically switch the behavior (per screen) when the screen is vertical in such a way that touching the top edge will tile the window to the top half of the screen and touching the bottom edge tile it to the bottom half. To maximize the window we can either touch the right or left edge of the screen.
