What's Changed
Highlights
🪟 **Lay out notebooks in columns!** Thanks to work by wasimsandhu, you can now arrange cells into multiple columns while editing — use your screen real-estate to the fullest! ([Docs](https://docs.marimo.io/guides/editor_features/overview/#editor-widths).)
📃 **Edit notebooks using your own editor.** Announcing initial support for one of our most asked-for features: you can now edit notebook files [using your editor of choice](https://docs.marimo.io/guides/editor_features/watching/) (neovim, Cursor, VS Code, ...) and stream changes to a running edit session. To opt-in, start your edit session with `--watch`:
bash
marimo edit --watch my_notebook.py
When editing `my_notebook.py` in your text editor, changes are sent to the browser on save.
Expect quality-of-life improvements to the external editor experience in the future.
🏃 **Re-run all cells.** A new command in the command palette lets you re-run all cells; you can assign a keyboard shortcut to this in the notebook settings.
