Your Mac notch is empty black space. This puts a pair of cute eyes there. They follow your cursor, blink, and look sleepy when you step away. Click them and you get the useful stuff: a focus timer, a clipboard, a shelf to hold files you are working on, music controls for Spotify, Apple Music, and YouTube, and a simple view of which apps you used.It stays in the notch. No extra window. The eyes are the fun part. The tools are why you might keep it.
