Help with a couple questions

[neurotrama]

Hello, I have been reviewing your library for an upcoming project and it is amazing!

I have a couple questions;

Is it possible to add a termination for the line, like an arrow?

Is it possible to make lines clickable?

I need to be able to create nodes with multiple parents. I have looked through your tree model, have you thought about using a DAG (Directed Acyclic Graph) for the model to allow for a multi-parent approach?

If you haven't could you point me to the location for the draw code and model to modify the structure to a DAG?

Thanks for creating such a great library!
