FocusParent action (like in i3): Without this sometimes it is simply impossible to swap the elements one wants (e.g. when having 2 windows on the left and 2 on the right, each in a split and wanting to swap these two window pairs) and in other cases this is more convenient than having to first focus something else to get the desired effect. With it the user can apply actions not only to leafs but also to nodes, thereby being able to manipulate splits that only contain other splits and no leafs (windows)
