I personally removed the app together with Hazel as I want minimal software to run on my system and my menu bar is already hidden at all times.<p>Wasting CPU cycles hiding some menu bar items seems rather wasteful. Although the menu bar search thing does seem useful.
This is quite the update - very sleek. My favorite new feature is the "show on hover". Just put your mouse where the icons should be and the appear like magic!<p>It really cleans up an already improved menu bar in macOS Big Sur.
