NavigationBuilder class scope

[muak]

I would like to extend the NavigationBuilder class, but currently I cannot create subclasses because of the internal scope.
I would appreciate it if you could change the scope of the NavigationBuilder class to public.

If I can create subclasses, I will be able to complete this in individual projects without affecting the source code, such as #96 .

Can you provide some examples and insight into what it is that you're trying to extend?

[muak]

What I wanted to extend is #96 .
This was merged so I no longer need to extend it.
Thank you very much.
I don't have any other examples of this at the moment.

I will report back if I need more.
