There is a thing really missing at the Review-Tools-edit pages.
There're a lot of pending edits (usually > 100) and raised flags (usually > 200).
Most of the flags and edits I can't solve as I have zero knowledge in that tag(Yes, I know approve edits and flags don't have to be related to knowledge, but it's still exhausting to read questions in a "foreign tag").
I would add a tag filter for the flags and edits. This is an exellent way to reduce the flags weight from the mods, and improve the flags handling quality (I'm sure a flag handled by the users of the tag, is better than moderator handled in a "foreign land").
(If that feature request get implemented, I would add a badge for solving X flags\edits in the tag Y, but that's for than.)
