Currently the user profile show Questions asked by the user and Answers posted by him/her.
Since users can now suggest edits as well, I think it would be good idea to add "Edits" section as well, showing what posts the user has edited or suggested to edit.
Not sure if to apply this to all users or just <2K rep users that can only suggest an edit - want your opinions on this matter. :-)
Just noticed that such information is available in the Activity tab but still, would be nicer to have it in the main tab as well.
