If I go into the 10k tools, I can see the number of flags for offensive and spam for all flagged posts. Is there a reason why I can't have this information in the flag window as well, so before I choose a reason, I can see how other people have flagged a post? It would be just like the close window - it shows you the number of people who have voted for each of the close reasons and the total number of people who voted.
It used to work that way - anyone with enough rep to flag could see the current flag count. AFAIK, it was changed to the current system in an attempt to reduce flag abuse...
