I find that the blueprint editor is not easy to use. It leaks some useful features for complex node network.
- Auto layout(not Alignment) selected nodes. Many people waste much time to rearrange the nodes.
- Length of connecting restrict. It will help to avoid spaghetti-like connecting.
- Global step backward/forward like most code editors. When there are many opening tabs, it is hard to go back after driving into a node in other class.
