The two layout selection options are replaced by a ListGroupPreference that allow to enter an arbitrary amount of layouts. The "switch_second" and "switch_second_back" keys are replaced by "switch_forward" and "switch_backward", which allow to cycle through the selected layouts in two directions. Layouts are changed to place these two key on the space bar. The backward key is not shown if there's only two layouts.
