Thanks for sharing! I'm one of those folks who has a directory of text file notes (they happen to be markdown files). Looking at the site, though, it's not clear why I would want to use this. It demonstrates 4 commands: (edit: not sure why my markdown isn't rendering in this comment)

* `hawth list`: why wouldn't I just use `ls`?

* `hawth show`: this would be `cat`

* `hawth append`: this would be `>>` (e.g. `echo foo >> note.md`)

* `hawth delete`: this would be `rm`, no?

Maybe there's more to it than the site shows, but just wanted to share my feedback at first glance. Hope it's helpful!
