What's Wrong?

Small quality of life improvement if typing /usage (or /us) autocompletes to /usage instead of /extra-usage. I think the /usage command is more likely used than /extra-usage, so with just a few letters that should pop up as the first hit.

What Should Happen?

Typing the /usage command should autocomplete to /usage and nog /extra-usage
