Wraps PDF.js with a feature-rich viewing and annotation layer: page thumbnails sidebar for navigation, zoom controls (fit-to-width, fit-to-page, custom %), text selection with highlight/underline/strikethrough tools, sticky note comments placed anywhere on the page, freehand drawing and shape tools (rectangle, arrow), and an annotations panel listing all markup with click-to-navigate.
Annotations are stored as JSON and can be exported/imported separately from the PDF. Supports dark mode for reading comfort. Keyboard shortcuts for all tools (H=highlight, N=note, D=draw, etc.). Responsive — annotation toolbar collapses on mobile.
