I have sometimes been taken to task by a site moderator for flagging something I'd previously flagged -- but the previous flag was raised and cleared so long ago that I had forgotten all about it, and nothing in the flag dialogue warned me. (Seriously, the site where this came up has posts that stick around for more than half a year in bad states. We're not talking about losing track of yesterday's flag.) So what happens is that I raise a flag, later look at my flag history, and see it and a previous flag.
I suppose I could dig through my flag history to see if I've flagged something before, but I've got a lot of flags (and a Marshal badge) and the history isn't searchable, so I'd have to page through it all. What I'd really like is some indicator that I've flagged this before, that would link to the right part of my flag history. (Or show the flags and responses some other way; I'm not picky.) The system already notices if I have another active flag on this post, so some "check for flags from this user" activity is already happening -- can we extend that to handled flags too and not just active ones?
Can we do anything to make flaggers aware of prospective repeat flags before clicking that final "flag" button?
