+### Key Requirements + +- **1:1 WebUI Port**: Exact same UI, features, and functionality as FlashForgeUI-Electron WebUI +- **Multi-Printer Support**: Full context-based architecture for managing multiple printers +- **Camera Streaming**: Both MJPEG proxy and RTSP streaming support +- **Spoolman Integration**: Filament tracking with per-printer spool management +- **GridStack Editor**: Customizable dashboard with theme engine +- **Config System**: Global settings + per-printer overrides +- **Cross-Platform Builds**: Support for x64, ARM64, ARMv7 on Linux/Windows/macOS + +### What NOT to Port + +- Electron desktop UI (renderer process) +- Desktop window management (BrowserWindow, etc.) +- Desktop notifications (native OS notifications) +- IPC handlers (Electron IPC) +-
