DockDoor

Hover the Dock, see your windows

April 19, 2026 · interface · dockdoor.net ↗

Hover the Dock to see live thumbnails of every window an app has open.

Shake-to-minimize: jiggle one window, the rest minimize out of the way.

Click an active Dock icon to minimize the front window.

Hover a Dock icon. A floating panel slides up showing live thumbnails of every window that app has open, with titles and a close button on each. Click a thumbnail to jump to that window — no Mission Control, no clicking-then-guessing.

Also includes a window-level ⌘-Tab replacement (Apple’s stops at app level), keyboard navigation through the previews, and configurable hover delays. Open source, MIT-licensed, free. The thumbnails update in real time and the animations are tuned to match macOS’s own — a rare port that doesn’t read as a port. macOS 13+.
