A lightweight macOS app/window/tab switcher and launcher triggered by Control+Tab (configurable from the menu bar). Press the hotkey to open a Spotlight-style popup, type to filter, navigate with the keyboard, and press Enter to go there — switching to the window or tab, or, for an app that isn't running, launching it. Press Control+Tab again to dismiss it. The list is sorted most-recently-used first.
