Sometimes, as a moderator, you read a post and decide not to edit or delete it for a special reason. An other moderator sees it and deletes it any way. It would be great if there was a mod which made it possible to leave a note to other moderators. (for example: please do not edit this post, or: the next time this user is getting a ban!)
It has to look different than a regular post and it should only be visible to moderators.
I hope you understand the idea of this mod (my english still sucks)
