If you're into plan9, and miss the old 9menu, I'd like to present 8menu! It's written in Go, and uses Fyne for the GUI. It lets you make simple button<-> action toolbars on the fly - https://github.com/donuts-are-good/8menu

There's bar(1), http://man.9front.org/1/bar, but that was added in September 2022.Googling, it looks like you might be referring to the Linux/Unix utility https://github.com/arnoldrobbins/9menu.
