If I'm not wrong, add_child adds a node in the last position of his parent. There's an additional function add_child_below_node that allows adding a node after to another specific one, so you can add a node in index 1, index 2, index 3, etc.. but never as first one.
Am I right?
How can I add a node at index zero, then?
Why there's no function for adding at specific index? Or at least for adding above node so we can use it to add as first node. Maybe I should add an issue on this, but I'm surprised there's no way to do such a simple thing and maybe there's a reason for it (couldn't find it tho)
Thanks!
