Jan 1, 2026January 2026 performance recap focused on improving drag UX, visuals, and stability across the tinymce/tinymce repo. Delivered four new features, addressed key stability issues, and reinforced maintainability with tests and refactoring. Key features delivered: - Draggable Component Enhancements: origin-based positioning (new origin prop with values top-left/top-right/bottom-left/bottom-right), overflow-aware behavior, safari-friendly selection, and drag start/end callbacks for Draggable and FloatingSidebar. - Iconography Update: introduction of new icons to improve UI clarity. - Spinner Dots Variant: added a new 'dots' type to Spinner and removed inline styles for maintainability. - AI Preview Loader UI Styling: fixed positioning, centered layout, and shadow effects for improved visuals. Major bugs fixed: - TINY-13520: corrected positioning CSS formula and added unit tests. - TINY-13547: improved selection handling in Draggable to resolve Safari-specific issues (user-select refinements and drag behavior tweaks). Overall impact and accomplishments: - Enhanced drag UX reliability and edge-case behavior across browsers, with smoother interactions during window resize and drag near viewport edges. - Improved visual clarity and user feedback through updated icons and loader styling. - Strengthened code quality and test coverage, enabling easier future enhancements. Technologies/skills demonstrated: - Advanced CSS transforms and origin-based positioning; cross-browser drag handling; drag-and-drop event wiring; UI polish and accessibility considerations; test-driven fixes and maintainable refactoring (removal of inline styles).

Dec 1, 2025December 2025 highlights for tinymce/tinymce: Key UI and internal API improvements delivering tangible business value. FloatingSidebar usability enhancements include removing the Popover API, fixed positioning, height controlled via CSS variables, and support for dragging beyond the viewport with partial visibility; tests updated to cover edge cases. Overflow handling improvements introduce Draggable.allowOverflow applied to FloatingSidebar to better manage viewport boundaries. Added an internal API in the theme manager (getSinkElement) to access DOM elements for dialogs/popups, enabling safer internal wiring and testing. These changes reduce UI fragility, improve theming/DOM access for internal components, and enhance developer productivity through clearer behavior and testing.

Oct 1, 2025Concise monthly summary for 2025-10 focused on features delivered, bugs fixed, impact, and skills demonstrated. Key UI/UX delivery centers on a new Draggable UI framework and a FloatingSidebar with precise initial positioning, enabling configurable, boundary-bound dragging and improved editor customization. Also stabilized behavior by reverting a prior fix that made accordions interactive in a disabled editor, ensuring consistent non-interactive behavior where required and cleaning up related tests/configs.
