I'm always open to suggestions, but rating an extension 2 stars just because it doesn't have a feature you want doesn't seem like an appropriate way to go about asking for a feature.

EDIT: I see you've updated your review. Very well, I can accept this kind of criticism. I originally intended to make this add-on as simple as possible, but it's true that such a feature could come in handy.

UPDATE: As of v1.5, this feature (copy to clipboard) is now available.
