As for this feature, I feel TL 4 shouldn’t even be seeing this option. But it is hard to say what the original intent was (I haven’t looked at the code yet).
eviltrout FEATURE: Show a button to Staff for “Moderation History” on posts/topics
I can’t speak for other Moderators, but I wouldn’t mind if the non-Moderator members we’re considering for TL4 could see what action I did. But exposing information related to the account an action was taken against would be TMI IMHO
EDIT
the translation is also missing for the post wrench menu.
