It would be inconsistent as it would only show for you on your own profile.
Seems like a pointless addition.
Profiles are mostly for other users to interact with, not so much the profile owner.Ideas and Suggestions are never "pointless".
I do not see any inconsistency being able to view a "Your Account"-Tab when viewing your own Profile-Page.
Please move this thread into "Addon Requests" if you think it does not fit into "Suggestions". Thanks.
