HyprKCS

lightweight, open-source graphical keybind manager specifically designed for Hyprland, a popular dynamic tiling Wayland compositor on Linux. Built with Rust and GTK4 (following Adwaita design for a native look), it provides an intuitive interface to view, edit, search, and organize keybindings by automatically parsing the hyprland.conf file (and sourced configs). It also serves as a cheatsheet, helps with migrations, and includes features like input device configuration.
