Jun 1, 2025June 2025 Monthly Summary — lichess-org/zulip Overview: Focused on stabilizing UI/UX, enhancing accessibility, and ensuring data accuracy for web-public streams and public-channel search, delivering measurable improvements in usability, discoverability, and reliability. Key features delivered: - Implemented web/public channels filtering for search suggestions and corrected public-channel display strings (commits ec82c543fe4fa714e749332415e7637e892239a6; 40ff1220efeb25587ffd78db4702071f5a0c651a). - Enhanced accessibility for social authentication: added tabindex and Enter-to-submit behavior for account email forms (commit fd355e2028ce14c39e325557d300804dd3160d24). - Added tracking of web-public streams within an organization to keep a current list for web-public access (commit b0eefb8a311f8e0a2b5ac7db49cac018847552f7). - Adjusted overscroll behavior to disable vertical overscroll while allowing horizontal overscroll for swipe gestures (commit ecce22f68546e569dc7b7e99e7d11fcab717757d). - Todo/Poll widget modal UI bug fix: resolved scrollbar overlap with modal content and focus outline cutoff for better readability and usability (commits 146dcbc33a80fd16f488c4ed17ab87f7d04df821; 51819459e9422277245715224a5eaff08d54d07b). Major bugs fixed: - Todo/Poll widget modal UI: fixed scrollbar overlap and focus outline cutoff, improving readability. - Tooltip detach stability in buddy list: fixed tooltip getting stuck on redraw when target is removed. - Bulk read flag updates: ignore near operator during bulk updates to ensure correct behavior with near filters. - Overscroll handling: ensured vertical overscroll is disabled while horizontal overscroll remains for swipe gestures. Overall impact and accomplishments: - Improved user experience and reliability in Zulip-backed UI: clearer public-channel discovery, more accessible authentication flows, and more stable UI interactions. - Enhanced data accuracy for web-public streams and read states, reducing risks associated with stale data and misapplied filters. - Accelerated developer workflows with clear change traces and improved consistency across UI fixes and feature work. Technologies/skills demonstrated: - Frontend web development with JavaScript/TypeScript and UI/UX considerations. - Accessibility practices (keyboard navigation, tabindex, and Enter-to-submit flows). - Mutation observer handling and robust UI behavior under dynamic changes (tooltip/buddy list improvements). - Data-tracking and feature-flag-like quality: keeping current org state for web-public streams and robust filter logic.

Feb 1, 2025February 2025 highlights for lichess-org/zulip: Implemented Left Sidebar Tooltips Module Refactor by extracting tooltip logic into a dedicated module left_sidebar_tooltips.ts. This isolates tooltip behavior and enables independent initialization/display for left sidebar items (e.g., unread counts and expand/collapse actions). Result: reduced coupling, improved maintainability, and clearer paths for future tooltip enhancements. Key commit: 1545a75645d8a765175068d6fa9fd7b5f1feccc6.
