Node editor: Show suggestion/searchbox when dragging from input/output sockets into empty space

Currently when working in the node editor if we want to add a node we do it trough the menu or the search box we can popup with shift+a shortcut. Then when we have our nodes we connect them.

I believe workflow can be improved if we can add nodes by simply dragging from a socket and auto connecting them.

How this would work:
1 User drags from any socket and releases the line in the work space.
2 Blender shows the search/list box of nodes.
3 By pressing a letter or typing a complete keyword, the list is then filtered by nodes the user is interested in.
4 After selecting the node the user wants, the node is added and the line automatically connects to the first matching socket.
5 The user can then cycle between sockets of the same type by using [Tab] or the [Up] and [Down] key.
6 When satisfied the user can simply hit enter or click the work space to finalize the action.

Motivation:
Rather than creating nodes first and then connecting the lines you can focus on setting up nodes in larger parts faster without having to go back and forth between connecting lines.
