Really cool idea. I'm not finding any links to source. Is this proprietary? I can't recall if brew allows proprietary stuff so that threw me off.<p>I recall something like this for GNU/Linux, but I don't think I ever got it working. I remember you had to set your DE to Unity (just via an env var), and then I think you could access the contents of menus via rofi once set up right. I have a script like the emoji selector already, but being able to select buttons and menus in arbitrary graphical programs seems like the real killer feature here.
