That is not a weekend's work, with an AI app builder or without one. That makes this kind of software worth paying for, not this one in particular: 15 of the 28 other window managers and launchers grade higher. - You could not: Control over other apps' windows. - You could not: A native app living in the menu bar. - You could not: A real app for macOS. Something home-made would be a web page. - You could not: The depth: we grade its features B, which means it covers the whole job.
