Good feedback! I’ve added this now in the code. It was only for post authors before. Now an admin gets a star icon, author a pen icon.
A quick fix is to add this to your style.css: (Replace the block that has /* post author comment /* above it – around line 1300)
/* post author & admin comment */
.commentlist li.bypostauthor > .comment-body:after,
.commentlist li.comment-author-admin > .comment-body:after { background: #3b8dbd; display: block; position: absolute; content: "\f040"; color: #fff; line-height: 12px; width: 12px; font-style: normal; font-family: FontAwesome; text-align: center; }
.commentlist li.comment-author-admin > .comment-body:after { content: "\f005"; /* star for admin */ }
.commentlist li.bypostauthor > .comment-body:after,
.commentlist li.comment-author-admin > .comment-body:after { top: 32px; left: -28px; font-size: 10px; padding: 2px; -webkit-border-radius: 3px; border-radius: 3px; }
.commentlist li li.bypostauthor > .comment-body:after,
.commentlist li li.comment-author-admin > .comment-body:after { top: 22px; left: -26px; font-size: 8px; padding: 1px; -webkit-border-radius: 2px; border-radius: 2px; }
