"This is great news - even though there is no way to sort them via the "headers" (good enhancement, perhaps?) as some of my posts are slightly out of chronological order (I assume these should be in descending order - most recent, first)."
Agreed! Search has 'Sort By:' capability including, Newest, Oldest, Highest Rated. Adding Sort By capability to 'View All My Posts' would be a good enhancement.
