There was a question recently that necessitated a comment being put into the parent post.
When I initally added the Moderator Note
comment, there were 12 more comments there than there are now. This meant that for someone visiting the post, they'd have to expand all comments, and find the important comment about the state of the post at the bottom.
I fixed it by deleting the meta-discussion comments, but I'd rather there be a better way.
This is also not the first time I've had to do this, it's just the first time I thought about a better way.
Feature request: When a moderator leaves a comment on a post with the prefix Moderator Note: in bold, the comment should appear even if the comments are collapsed, at the end of the collapsed comments (or at the beginning, but it'd be less weird if it appeared at the end).
