Mark and annotate PDFs with a built-in eye tracker for automatic scrolling

Lightweight and easy-to-use toolset for creating notes on PDFs in the Google Drive with a toggleable eye tracker to scroll pages automatically. Originally designed for reading and annotating music, its versatile features make this extension useful for any purpose regarding marking-up PDFs. Keybinds: - Horizontal Dividers: double click on page. Allows the user to create eye-catching labeled dividers that can easily be sifted through using the toolbar to get back to where you left off. To delete a divider, simply click it once and press backspace. - Notes: shift-click on page. Creates a blue textbox anywhere. To delete a note, click it once and press backspace. Eye Tracker: This extension uses a client-side eye tracking library, meaning that all processing occurs on your browser, not in a cloud, ensuring the safety of your camera. To turn on the eye-tracker, press the eye icon on the toolbar when a PDF is opened. To turn it off, click it once more. The parameters for eye tracking can be set in the popup for this extension. It is important to calibrate your camera beforehand by clicking the "Calibrate (9-point)" button in the popup. To adjust the scrolling threshold, use the slider in the popup and toggle on/off Scroll Up or Scroll Down. To view how the eye-tracker will scroll, toggle on the debug option in the toolbar when a PDF is opened.
