 ### Requirements
 
 - Using [`GtkStackSwitcher`](https://developer.gnome.org/gtk3/stable/GtkStackSwitcher.html). If the 
application is using a box of 
[`GtkRadioButton`](https://developer.gnome.org/gtk3/stable/GtkRadioButton.html)s or something similar, it 
must be migrated to [`GtkStack`](https://developer.gnome.org/gtk3/stable/GtkStack.html) and 
[`GtkStackSwitcher`](https://developer.gnome.org/gtk3/stable/GtkStackSwitcher.html) first.
