Folder Peek
The Dock folder behavior macOS forgot to ship
Pin folders to the macOS menu bar with the niceties Dock stacks have always lacked: file thumbnails, Quick Look on hover, fuzzy search across the directory, and quick actions (reveal in Finder, copy path, move, share) on each row. Multiple pinned folders means the menu bar doubles as a bookmark bar for places on disk — Downloads, the active project, the screenshots folder, that one git repo you keep poking at.
Not a Finder replacement, just a 200-pixel-wide window into a folder you check often. macOS only, one-time purchase via the App Store.
