Score: 6.8/10 (Innovation: 6, Technical: 7, Documentation: 8, Utility: 6)

KeyGhost is a macOS menu-bar app that turns a physical key (like Caps Lock) into an application launcher with a visual overlay, reading input directly from the HID layer to bypass key remapping tools. It's interesting for its novel approach to keyboard-driven app launching and its technical handling of low-level HID events and event tap consumption.
