Can the list of reported items have a complete overhaul and use the standard view and filter options that the rest of the forum now uses?
My suggestions, as crudely shown in the above picture:
1. Add a Reported By/Reporter column - this is to easily identify who has reported the content. Perhaps with their avatar too??
2. Add a filter option - like in the main forum.
3. Eliminate the sidebar - like option two, this would create a uniform view of content.
