It functions as a low-level input hook that intercepts keyboard and mouse events at the OS level to trigger custom window management actions. The project includes a coordinate-based grid mapper for precise snapping to custom zones and an input remapper that assigns keyboard scan codes to virtual mouse buttons. It also features a window automation CLI used to trigger management tasks on foreground or targeted application windows. The tool provides window layout management, dynamic window control to move and resize windows via modifier keys, and input filter middleware to restrict actions based on application blacklists, process names, or window titles. It further enables control over system volume and window transparency through mapped input triggers. ## Tags ### Software Engineering & Architecture - [System Input Hooks](https://awesome-repositories.com/f/software-engineering-architecture/event-driven-hooks/system-input-hooks.md) — Intercepts raw keyboard and mouse hardware events at the OS level to trigger custom window management. ### User Interface & Experience - [Window Managers](https://awesome-repositories.com/f/user-interface-experience/window-managers.md) — Organizes application windows using a configurable grid and snapping zones to optimize screen real estate. - [Coordinate-Based Positioning](https://awesome-repositories.com/f/user-interface-experience/coordinate-based-positioning.md) — Calculates precise window positions and dimensions using a grid coordinate system for snapping. - [Window Snapping Coordinates](https://awesome-repositories.com/f/user-interface-experience/coordinate-based-positioning/window-snapping-coordinates.md) — Calculates window positions and dimensions using a predefined coordinate system for precise snapping. - [Modifier-Conditional Mappings](https://awesome-repositories.com/f/user-interface-experience/form-and-input-management/input-handling/secondary-modifier-keys/keyboard-input-mapping/modifier-conditional-mappings.md) — Maps mouse movements and clicks to window resizing or movement based on active modifier keys. - [State Trackers](https://awesome-repositories.com/f/user-interface-experience/modifier-key-simulators/state-trackers.md) — Monitors the real-time status of modifier keys to determine when mouse movements should resize windows. - [Native Window Layout Management](https://awesome-repositories.com/f/user-interface-experience/native-window-layout-management.md) — Aligns windows to predefined custom zones or a configurable grid for efficient screen organization.
