Mantle is a cross-platform desktop application for discovering and controlling LIFX smart lights over your local network. Built with Rust and egui, it offers real-time light management alongside unique ambient features like screen-color sync, audio-reactive lighting, saved scenes with scheduling, global keyboard shortcuts, and a system tray for quick access. Born from the ashes of lifx_control_panel.
