### 07 April 2021 Weekly Meeting

- Isabela
- Accessibility meeting is today fifteen minutes after this call!
- Current work in progress includes `skiplink`, [#9622](https://github.com/jupyterlab/jupyterlab/pull/9622), and figuring out automated testing strategies.

- Mehmet
- Galata is now integrated with ipywidgets and bqplot. Used for visual regression testing for PRs, via GitHub Actions
- Integration to ipywidgets
https://github.com/jupyter-widgets/ipywidgets/pull/3172
- Example run in ipywidgets
https://github.com/jupyter-widgets/ipywidgets/runs/2235751369?check_suite_focus=true
- Integration to bqplot (done by Martin @ QuantStack)
https://github.com/bqplot/bqplot/pull/1311

- Tony
- react aria for accessible react components https://react-spectrum.adobe.com/react-aria/
- Ani
- Demo of Kernel Specification Manager and feedback!

- Jason
- On HackMD, disable "nyan cat" and "power mode" by clicking on the wrench in the status bar
- [Support notebook format 4.5 (cell ids)](https://github.com/jupyterlab/jupyterlab/pull/10018)

- Jessica
- User experience of name notebook on save
- https://github.com/jupyterlab/jupyterlab/issues/5207
- https://github.com/jupyterlab/jupyterlab/pull/10043

- Mike
- How do we work with extra columns/decorators in the file browser:
- example issues/PRs:
- jupyterlab: ["toggle last modified column" does not work](https://github.com/jupyterlab/jupyterlab/issues/8860#issuecomment-809672555)
- jupyterlab-git: [add colours for added/modified/deleted files in file browser](https://github.com/jupyterlab/jupyterlab-git/pull/885#issuecomment-787462919)
- also show the number of linter errors?
- possible solutions:
- current approach: inherit from file list renderer and swap the default renderer? does not work when multiple extensions try to modify it
- better approach: add a lumino's Signal as a hook in the renderer to add custom columns and decorators in extensions?
- proposal: add columns as a first-class citizen, expose API like `registerColumn()` and `toggleColumn()` (issue to be created)
- question: is the new regular-table based [tree-finder](https://github.com/telamonian/tree-finder) coming anytime soon? (Max?) Can it support these use cases? -> Answer: targeted for 4.0, might be available earlier; good to open enhancment proposals there (in tree-finder)

**Additional Discussion**
- [4.0 Roadmap discussion continued](https://docs.google.com/spreadsheets/d/1r6_ySd18xZwfPexdmlkdFhHUWynaza0zXjrxMMIoLWw/edit#gid=0)
