Drag and drop onto connections
Right now if you select a connection, and then click one of the simple nodes in the quick bar, it splits the connection and adds the node into it, which is super useful! However, this doesn't seem to work for more complicated nodes pulled from the Library, and, additionally, when you drag a node (whether a basic one from the quick bar or the library), it highlights the connection as if it were going to do exactly what I would want and expect, but upon dropping the node it simply drops it on top of the connection without splitting it. It would be great if dropping a node onto a connection behaved the same was as selecting the connection and then adding the node (and, additionally, work for nodes coming from the Library)
