Custom node appearance and event handlers. Proof on concept: Inline Gauge

I am most certainly always open to new ideas. :slight_smile:

Shall we take this to a new thread to discuss? I'd like to understand a bit more about your idea, not sure I've entirely grasped it yet.

There is something on the backlog I've had for quite a while (I think it is still there - the backlog is a bit large!) to help facilitate 3rd-party nodes for uibuilder. So certainly worth a discussion.
