## Description

LibreraReader is a multi-format e-book reader and digital library manager designed for mobile and desktop devices. It functions as a customizable document renderer and a text-to-speech document player that converts written text into spoken audio via a configurable speech engine and integrated media player.

The project distinguishes itself through a high degree of visual and functional customization, including the ability to inject custom CSS for styling overrides and the use of pluggable rendering engines to balance speed and stability. It includes specialized navigation tools such as a vertical scroll-lock mechanism and automated page scrolling for hands-free reading of text and music scores.

The application provides a comprehensive suite of library management tools, including automated folder indexing, metadata filtering, and document format conversion. It supports academic and research workflows through integrated online and offline dictionary services, translation tools, and document annotation features. Reading progress, bookmarks, and application settings are maintained across multiple devices via cloud-based synchronization.
