Pop up feature for nodes.

### Feature Idea

Please make a feature to pop up nodes so people who work with multiple screens can have the workflow in one screen and see the result in full screen in another one.

I'm tired of zooming in and out for every little parameter change I make 🙈

The issue names no files, tests, or entry points, so begin by locating the node-editor and canvas UI in the repository. Define the interaction and rendering scope for popping nodes across screens, then document an agreed completion criterion before implementation.
