Custom node pin location

Hi,

When creating new nodes in a node_editor, would it be possible to allow the location of the pins (input and output) to be user-defined such that they can be located anywhere along the edges of a node? I ran into an issue in my project, where the node hierarchy/network would be more user friendly if the connections would run top-bottom, rather than left-right.

Currently I don't see any workaround for customizing the locations of the input and output pins for a node widget, other than being on the left or right side.

Thank you!
