Problem: I would like to know which of my edits have added the most amount of bytes. I don't mean the pages I have lots of edits on, I mean which single edits have added the most content. However this option is not available in XTools or Wikistats.
Proposed solution: Add a new tool to XTools that lists a users edits by their diff size.
Who would benefit: People who want to know statistics about their largest edits.
