 * to manage the visibility of them too. But the way that we did before was to
 * widget->hide(); something, and if you hided something using the splitter,
 * by holding it's handle and collapsing the widget, then you used the 'ctrl+number'
 * shortcut to show it, it whould only show a gray panel.
 *
 * This patch makes everything behave using the splitters.
