• Tony:

  • Bi weekly live stream on working with Lab extensions (2pm EST) https://youtu.be/4445MZkNszY

• Brian:

  • UX of single document mode
    • Let's open 1 issue, as there are many subtle, interrelated aspects)
      • Feedback for single-document/classic notebook mode in 3.0 jupyterlab#9117
    • Not sure that "single-document mode" really captures the idea well, maybe "Classic"?
      • "Zen mode" is common as well. "Focus mode"?
      • Does new Jupyter users know what "classic" implies?
        • We've been putting a lot of branding effort into calling the Jupyter Notebook "classic"
    • Other extensions add content to that space, not sure how it will scale.
  • RTC+Yjs
    • I am going to start working on integrating Yjs into JupyterLab master.
    • I have met with the lead of Yjs (Kevin) and talked about porting relevant aspects (schema's specifically) over to Yjs, Python implementation, etc.
    • Ny focus will be on getting working RTC+undo/redo to users as fast as possible, with as few breaking changes as possible.
    • PRs to master, but also possibly separate extensions that work before 4.0.

• Discussion

  • JupyterLab release timeline
