What's Changed
Highlights
🏠 Edit multiple notebooks with marimo edit!: marimo edit now opens a notebook homepage that lets you create new notebooks, and start and stop exiting ones. That is, this homepage gives you a single marimo server to edit multiple notebooks.
You can still use marimo edit notebook.py to edit a specific notebook. To create a new notebook without going through the notebook server, use marimo new.
This feature is new and will evolve rapidly — please give us your feedback!
🗂️ File browser: Use mo.ui.file_browser to add an interactive file browser to your notebooks! Thanks @wasimsandhu for the contribution!
Quality-of-life improvements: Version 0.4.0 includes accessibility updates to mo.ui.number, lets you format notebooks with ruff (in addition to Black), and other small improvements.
