Thanks. Linting sounds great during design time. I'll take a look.
@TotallyInformation As for the purpose, our custom node lib includes node clusters that are supposed to work within their own circles, so some kind of barricades are needed. I'd like to improve the affordance with explicit barricades so that people learn the node combination and the correct in/out port mapping with intuition as much as possible.
Although there are the on-hover port tooltips and the help doc pane on the sidebar, those are not straightforward enough for my audience. So I'm looking for more obvious options.
