Make sure the nodes are not overlapping and that the connections are at the same index as the nodes.

Hi,
Could you add a function to ensure that the nodes do not overlap or add a small space between two nodes? This way, if I try to move a node, I won't be able to drop it directly in front of another node. Additionally, I want the connections to remain at the same index as the nodes so that when I move a node around, I will always see the connection.
Issue like this:
