 ### Features
 
+- Mobile layout & PWA — responsive editor with touch-optimized toolbar, swipeable bottom drawer (layers/properties/design/code), HUD overlay, and installable PWA with icons and service worker
 - Tailwind CSS v4 JSX export — export selections as HTML with Tailwind utility classes (`<div className="flex gap-4 p-3">`) from the Code panel, CLI (`bun open-pencil export --format jsx --style tailwind`), or programmatically via `sceneNodeToJSX(id, graph, 'tailwind')`. Supports layout, sizing, colors, border radius, opacity, rotation, overflow, shadows, blur, and typography. Uses v4 spacing semantics (px/4 multiplier) with automatic fallback to arbitrary values.
 - Code panel format toggle — switch between OpenPencil (custom components) and Tailwind (HTML + utility classes) output
 - Homebrew tap — `brew install open-pencil/tap/open-pencil` for macOS (arm64 + x64), auto-updated on each release
+- Double-click to rename layers — inline rename in layer panel, shared `useInlineRename` composable
 - New AI/MCP tools: `analyze_colors`, `analyze_typography`, `analyze_spacing`, `analyze_clusters`, `diff_create`, `diff_show`, `get_components`, `get_current_page`, `arrange`, `node_to_component`
 
 ### Improvements
@@ -14,6 +16,10 @@
 - Split tools into domain files (read, create, modify, structure, variables, vector, analyze) — easier to navigate and extend
 - Replace inline type definitions with named types (`Color`, `Vector`, `SceneNode`) across the codebase
 
+### Fixes
+
+- Fix drawer animation jump on close — single spring transition instead of two-phase
+
 ### Internal
 
 - Add `motion-v` for declarative animations — used in mobile drawer (spring-animated height with pan gestures) and toolbar (layout-animated category switching with directional slide transitions)
