Instead of having it add a node at the very bottom of a stack of nodes you have up. Maybe have it where the node is added to where you are looking at. It kinda sucks when you are working out a bug at the top right of a heap of nodes and you have to add something and it scrolls all the way down to the bottom left 3 miles away to add a new node. Which adds more work to your workload because you got to drag it all the way back up to where you were looking at.
