Declarative DSL building native menu bars with cross‑platform fallbacks, shortcut and icon helpers, per‑platform visibility flags, out‑of‑the‑box macOS defaults and localized labels.

Minimal placeholder repository awaiting documentation; scaffolds codebase and configuration, intended for future features and contributions, currently lacking descriptive README and usage examples.

Unified API for scheduling and managing background tasks—one‑off, periodic, exact and chained jobs—featuring advanced triggers, structured logging, event‑driven completion, demo UI and docs.

Onboarding showcase toolkit enabling declarative, step-by-step UI highlights with captureBounds targeting, customizable highlight shapes/styles, flexible composable content, intelligent tooltip positioning, and simple controller-driven sequencing.

App store and signer ecosystem offering declarative UIs, dependency injection, MVI state management, networking, local persistence, asset/package handling, and modular shared libraries for app distribution.

Unified, type-safe Mixpanel analytics wrapper offering a single API for tracking events, properties and purchases, with simple initialization and flexible event/property mapping.

Production-ready UI components, theming, and design tokens for consistent interfaces; brand assets, iconography, Figtree typography, spacing, shadows, radii and opacity tokens.

Shared declarative UI and app scaffolding enabling common business logic, target-specific implementation folders, native entry-point integration and straightforward build/run workflows.

High-performance, lock-free bounded priority queue using persistent treap and CAS-based atomic updates; automatic eviction, key-based upsert deduplication, O(1) lookup, reactive state and batch mutations.

Customizable color picker dialog returning hex color strings for easy persistence, offering initial-color control, adjustable dialog properties, and a compact composable UI for seamless color selection.

Compose physics-enabled layout applying gravity and collisions to composables, with per-child shape/mass/bounciness configuration, tilt-controlled gravity, bounds, draggable/flingable interactions, and configurable physics state.

Renders and inspects @Preview composables on-device or headless, offering pixel-accurate screenshots, interactive inspector, rich hierarchy/semantics extraction, accessibility checks, and AI agent integration.

Unified low-latency audio engine with real-time, lock-free DSP: 16 built-in effects, hot-swappable effect chains, low-overhead callback I/O, streaming, real-time metering, file decode/encode.

Date/time parsing, formatting, arithmetic and humanized relative-times with immutable, thread‑safe API; auto-detect parsing, type‑safe formatting/timezone chains, boundary navigation, field setters, live Compose helpers.

Small focused responsive-layout toolkit: pick composables and values per screen breakpoint; adaptive navigation (bar/rail/drawer), two‑pane master/detail, conditional slots, testable breakpoint injection, customizable breakpoints.

Declare singleton schemas offering typed compile-time field access and serializable wire definitions; consumers decode, diff, compose, namespaced-merge, and walk entries without shared code.

Declarative, type-safe rich text editor engine with UI components handling dynamic edits: automatic span shifting, atomic mutations, semantic runs, paragraph styles, lists, and constraint-driven formatting.

Small MVI-style state container: immutable StateFlow state, single onIntent input, one-time effects, minimal contracts, store delegation, standalone stores, lightweight ViewModel/effect and saved-state helpers.

Global phone-number validation, region and country-code checks, E.164/international formatting, region/calling-code extraction and structured parsing — built atop native parsing libraries for accurate results.

High-performance lightweight SQL ORM with strongly-typed SQL DSL surfacing compile-time errors, automated entity mapping, bundled SQLite drivers, expressive querying supporting joins, aggregates, transactions.

Bridges the gap between multiplatform and platform-specific libraries, offering unified APIs for AlertDialog and DropdownMenu, enabling consistent code across platforms without modifying stable APIs.
