The reason for putting labels into the config file is for internationalization purposes. As a rule (tell me if I've missed any spots) I keep the templates language-free. Meaning, any visitor-readable word is made into a variable. That's why you see something like this in the template file:
$label_find:find
With this system it's just a matter of translating the config file to allow other languages.
Sincerely,
Carl
