caused auto connect to not work in some cases, because that now orders nodes and only connects if the new node is to the right of the old node. I doubted between always connecting to the new node as output or keeping this ordering trick also when adding nodes. Decided on the latter because then you can also add a node between two others and have it auto connect to both.
