Visit [Discourse](https://discourse.jupyter.org/t/jupyter-community-calls/668) for more information. The unofficial prompt is tutorials, how-to's, and things you wish you knew when starting in the community. - Tony - RTC Workshop https://hackmd.io/UbnBH58hS8itoWgfiWT77A - **Additional Discussion** - - [4.0 Roadmap discussion continued](https://docs.google.com/spreadsheets/d/1r6_ySd18xZwfPexdmlkdFhHUWynaza0zXjrxMMIoLWw/edit#gid=0) - - ### 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?
