Commentify Blog Comment Reply

What I like: -Email alert to commenter when someone replies. -Users can comment with just email, without signing in to anything. What I don't like: -Reply alert emails' sender is name=[store name], address="no-reply@batulcreation.com", instead of store email address. Missing features: -Import & export comments. -Insert hyperlinks and images in comments. Would be nice to have a markdown/rich text editor with at least bolding, italics, links and image insertion. -Edit comments. -Upvote/downvote comments.
