Hey,
I’ve just updated to v 1.2 with some new features; being able to edit comments and an option to only let registered users report comments.
As for the BUG, I haven’t found a solution that I’m happy with yet. Adding it to comments_text doesn’t look as good as comments_reply_link. I’m gonna try to find a good solution to it next.
After that I’ll add ability to see what user reported the comment and an optional field to add reason for reporting.
