ReadPaper Utils por Shinemoon

This tool connects to the M5Stack PaperS3 e-ink reader to streamline device management. Two core functions are accessible via the taskbar:

1. File Management: Browse and manage device files (texts, fonts, lock screens). Requires a PaperS3 device running Readpaper firmware in Wi-Fi hotspot mode; the UI auto-hides when disconnected.
2. Font Converter: Convert standard fonts (.ttf/.otf) into compressed .bin format optimized for PaperS3's limited hardware. Features real-time preview with adjustable size and weight, generating downloadable files for manual upload.

Additional reading-related features are planned; current functionality already provides essential value.



本工具用于连接 M5Stack PaperS3 电子墨水屏设备（with ReadPaper固件），简化设备管理与配置。目前提供两大核心功能：

1. 文件管理：浏览和管理设备中的文本、字体、锁屏文件（见截图2）。需 PaperS3 设备运行 Readpaper 固件并处于 Wi-Fi 热点模式；未连接时自动隐藏。
2. 字体转换：将标准字体文件（.ttf/.otf）转换为适配硬件的压缩二进制格式（.bin），支持实时预览压缩效果及调节参数，生成文件可下载后手动上传至设备。
