Hi,
I just discovered this component and started working with it.

I understand that the whole concept of it is to initialize nodes on the go as they are needed but I need all of them to initialize instantly.

What is the smart way to do it?

The only thing I came up with is to use GetLast() after adding nodes.
I believe, there is a better way, or not?
