Have you had any milestone for this feature? Adding nested comment seems to be a great feature to be opt-in.
sorry, I am currently very busy so I will only implement features I need myself at the moment. You could work on some feature you want and start a pull request if you like, but wait with that until I redesigned this component to use widgets #6.
also this is duplicate of #14.
It's okay, hope you will be okay with your project. I'll come back later.
