The flag menu matches the close menu exactly. They change together and there has to be a need for there to be an item added to the list.
Stats of interest for our site:
- Super User : 14 migrations (21% rejected) (The flags I almost always act on)
- DIY : 5 migrations (20% rejected) (The flags have mostly been correct)
- Physics: 4 migrations (The flags have mostly been correct)
- Math : 4 migrations (25% rejected) (The flags have mostly been correct)
- SO : 2 migrations
Now, an important point, at least to me, is that these migrations only track those that a diamond moderator saw and approved. That means, and I know this to be the case, there are many many more "rejected" migrations for all of them. Sadly, I can not easily pull statistics on that so I have added a note.
Looking at this, it might make sense to add at least Super User, maybe even DIY/Physics/math. I will contact the SE comm team and see their thoughts.
