👋 Introduction

The application features a file browser sidebar for easy navigation, supports multiple formats (Markdown, MDX, and plain text), and includes convenient features like drag-and-drop support, recent files/folders tracking, auto-reload on file changes, and export to PDF.

This project is developed with Qt 6.x (Qt 6.9.3 at the time of writing).
