On the flag-summary page (aka flag-history), the wording "moderator attention flags" is very misleading, as this total is not "flag for moderator attention", as the name suggests.
It is a total of flags for both the review queue and "direct moderator attention".
I suspect the wording comes from when there were only moderators managing flags, and no community reviewing.
Suggest: Change wording to "total flags"
Example: My current flag-history on SO:
Your flagging history
154 moderator attention flags
142 deemed helpful
3 declined
I have only ever raised 2 flags to "moderator attention".
Propose Changing To:
Your flagging history
154 total flags
142 deemed helpful
3 declined
Simple and clear - total flags, which already includes total "flags to moderator".
I pondered over separating the flags, so "normal" flags and "flags to moderator" separate totals and breakdown. But they're all just "flags" to report a problem.
