Also, interfaces are not linkable.
e.g., for gtk.ApplicationWindow, it inherits from gtk.Window but
I have to go back to the packages and scroll down to find
gtk.Window to see it's properties and methods. Would be nice if I
could just click on the gtk.Window and it jump me to it.
https://api.gtkd.org/gtkd/gtk/ApplicationWindow.html
class ApplicationWindow : gtk.Window.Window,
gio.ActionGroupIF.ActionGroupIF, gio.ActionMapIF.ActionMapIF;
since the hierarchy is gtk/Window/Window, click on gtk should
take one to the gtk package, the first Window should take one to
gtk.Window and the second should take one to gtk.Window.Window
