Thanks Michal! I know this has pros and cons of course - say you update the grid for hyperparameter search: this will trigger cross validation again. Of course, in most of these DAG notebooks there are ways to switch this off - I guest most of the work for this feature would be providing a pleasant an functional UI. This seems more of a thing for JupyterLab 5, while it would be better to focus on things like [inline variable insertion](https://discourse.jupyter.org/t/inline-variable-insertion-in-markdown/10525).
