Show HN: Facad – A colorful directory listing tool for the command line

Facad is about functionality, not just aesthetics. Key features:

- Intuitive file type representation

- Smart sorting (directories first, then by extension)

- Four-column layout for quick directory analysis

It evolved from this alias:

  alias ls='ls -A -F --group-directories-first --sort=extension --color=always'

Facad takes this concept further, offering more flexibility and visual clarity.
