DockDoor

DockDoor is a free, open-source macOS utility that enhances window management through interactive Dock previews and keyboard shortcuts. It displays live thumbnails of application windows when users hover over their corresponding Dock icons. The software allows users to switch between windows, minimize them, close them, or enter full-screen mode directly from the previews. Its Alt+Tab functionality provides window-level navigation instead of switching only between applications. DockDoor also integrates with the native Command+Tab switcher to display windows belonging to selected applications. Additional capabilities include folder previews, media playback controls, and configurable appearance settings. Designed for macOS 13 and later, it operates locally without analytics or external tracking.
