docktor
Live window previews and glass-like widgets for the macOS Dock
About docktor
docktor makes the Dock a faster gateway to windows and information: hover over an app for live window thumbnails and one-click activation, or use them instead of the system Cmd+Tab window picker. It also puts music, calendar, and weather near the cursor, with controls for Spotify and Apple Music. For macOS 26.0（Tahoe） or later, it offers a Universal build, and core features need no account.
