It does for me, I see the same upvote/downvote/reply icons for each message, and they work in the inbox. Tapping the post title that appears on top of the message takes me to the post where I can see the comment along everyone else’s.

Finally, on the top right corner of the screen there is a double tick icon that marks everything read and clears the inbox
