Stylus friendly editing

[derkork]

Is your feature request related to a problem? Please describe.
When working with a stylus the current way of adding new nodes to the graph is less than ideal as it is more intended for a keyboard/mouse workflow.

Describe the solution you'd like
Ideally some kind of radial menu that would allow a stylus user to quickly select the node in question.

Describe alternatives you've considered
None.

Additional context
An example of a more stylus friendly interface would be BlockScad
