What is one thing in your subproject that really should be done in 2026?

• (+2) More contributors and reviewers especially
  • Or ways to scale our reviewing, perhaps using LLMs to help
  • Perhaps starting PR review meetings like the current issue triage meetings
• Easy to use UI library (like Material UI) for consistent UI elements people can easily use
• Enable JupyterLab researchers to use local AI models or in-cluster AI models
  • Better integration in general with AI tooling by default with builtin packages
• Move document and session state to the server
  • William polished and open sourced the realtime sync algorithm used by cocalc: https://github.com/sagemathinc/patchflow It’s a very different feel than yjs — much more like a revision control system.
