Month: 2025-10. Focus: gravity-ui/markdown-editor. Delivered UI stabilization improvements to resolve visual overlap by implementing a dedicated z-index strategy for popups relative to the sticky toolbar. Key changes include introducing a getTargetZIndex helper and a layout constant LAYOUT.STICKY_TOOLBAR to dynamically compute z-index values across editor components.

Month: 2025-04. This monthly summary highlights the key feature delivered in gravity-ui/uikit and overall impact. Summary: Implemented a new zIndex prop on Popover to control stacking order; updated PopoverProps interface to surface the API; this enables precise layering across overlays such as modals, tooltips, and dropdowns, improving UI consistency and reducing z-index related bugs in downstream apps. There were no major bugs fixed this month in the repository, but ongoing stability and compatibility checks were maintained. Overall impact: improved developer experience by enabling reliable overlay stacking, which reduces layout issues in complex screens and accelerates future UI enhancements. Technologies/skills demonstrated: TypeScript API design, component API surface evolution, commit traceability, and cross-component integration in a UI kit.
