Spotlight onboarding tours: dim screen with rounded cutouts, anchor explanatory tooltips with Back/Skip/Next, live target tracking, lifecycle-safe targets, customizable shapes, animations and labels.

Compose-style DSL for multi-page PDF generation with selectable text and vector output, top-down coordinates, simple drawing primitives (text, shapes, images), and small, standards-compliant files.

Painter loading images from URIs for Compose UIs, wrapping Coil in a minimal, preconfigured implementation focused solely on image retrieval without animation or extra features.

Gesture-triggered debug overlay to inspect logs, grouped events, HTTP traffic, and live session state; supports custom log types/renderers, real-time search/filters, custom triggers, and zero-overhead release stubs.

Rich text editing with plain and block editors, inline formatting, custom emoji, hyperlinks, tables, smart paste, JSON serialization, undo/redo, and floating toolbars for integrated UI components.

Experimental console UI builder using Jetpack Compose compiler/runtime — declarative composable primitives, state-driven rendering, live terminal redraws, built-in effects and sample interactive apps.

Generates vector PDFs with identical, selectable/searchable text, deterministic integer-layout and font subsetting, Compose-style DSL, automatic pagination, SVG/VectorDrawable vector import, tables, images and progress reporting.
