Every product still shipping buttons is legacy

Okay, let’s talk about that first command: sort all files in this directory by relevance. Relevance to what? Is this a permanent sort (what does it do to the file names?) or just a reordered ls output? What button in what OS is this superseding? Is this really an huge improvement over the smart search functionality in most OSes (besides requiring an open terminal and additional keystrokes for the abstractions)?

Some of these are slick despite not really being examples of the obsolescence of UX idioms. But that first one is a very strange example to lead with.

Didn't fans of Lotus slash commands say the same? :)
