It might be useful to be able to filter down to the suggestions that you made with a "My Suggestions" button (like the All Suggestions or Suggestions for the same page buttons) [Incidentally the capitalization between those should probably be consistent].
That way it would be easy to look back at suggestions you made in the past.
