Mar 1, 2026March 2026 performance summary for storybook repository focusing on UI consistency improvements in the toolbar. Delivered a targeted fix by reinstating the extra toolbar divider when zoom control visibility varies, ensuring visual parity across toolbar states. Implemented via revert of the previous removal (commit 04efb8bdd10b122945574ac1b039942d365076e4). This reduces UI glitches during component testing with different zoom levels and aligns with design guidelines.

Feb 1, 2026February 2026: Focused on stabilizing Vue integration in Storybook and cleaning up UI code. Reverted problematic reactive globals in Vue decorators to restore Storybook Vue 3 stability, removing tests and functionality tied to reactivity. Clarified UI behavior by removing an unnecessary separator visibility comment in the preview tool menu, streamlining code and reducing UI ambiguity. These changes reduce maintenance overhead, mitigate flaky test noise, and preserve the intended user experience across Vue 3 stories.
