Window minimization allows the element to be temporarly minimized and placed in the bottom left corner of the viewport. When minimized the window can't be dragged nor resized. The window can be restored to it's normal state by calling the restore method.
When multiple windows are opened the user can minimize those that are not in use in order to free the screen and see the background. Minimized windows are placed next to each other in a single line starting from the bottom left corner of the viewport. When a window has been restored, the minimized windows are re-aranged.
