Aren't users able to comment status updates? AFAIK they are, so it could have comment_count > 0The original suggestion already has a Profile Posts tab.
For the record, there is no distinction in the database between a "status update" and a "profile post" - they are all stored in the same format in the xf_profile_post table.
You could however run a query to extract all entries which have the same profile_user_id and user_id and a comment_count of 0.
That would extract all of the "status updates".
This looks nice, if someone can achieve to group recent status in a Tab like that, it would be easily expanded to a page:
yeah, everyone wants something else.
