* So, here's the deal.
* We have a few QSplitters that takes care of helping us with the
* size of a few widgets, they are ok, and we should continue using them
* 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.
