Wiggle a node free

[ErrorX]

In Houdini you can move a node back and forth to disconnect it.
This speeds up the workflow a lot. This would be a nice feature to have in Substance Designer.

also, when you want to remove the connections quickly in Houdini you could hold Y (default) and drag with LMB across the connections to create the line that cuts them - it would be very cool to see the same functionality in Substance
