Yup, Jed ignores these. We could always add category for now, in case we supported it later in `.pot` files? No idea if it is supported, but it does like most people don't use it. Both Jed and the python docs say this, and it doesn't seem gettext-parser supports this, so maybe we should just add the categories in these methods, and make a comment in the `potter.js` module that we don't support this yet?
