appkit-modern-input
Use when modernizing input handling in a macOS AppKit app — overriding mouseDown:/rightMouseDown:, hand-rolling mouse tracking loops with nextEvent(matching:), wiring selection / context menus / drag-and-drop by hand, fixing a control that won't respond to clicks (overlapping sibling views), broken Tab key-view navigation, or NSStatusItem status-bar items with a custom view or window. Targets modern macOS (macOS 26/27).
