What would the querystring be, ?filter_user=orangeandblack5&extra_posts[]=12345&extra_posts[]=12346? Where am I going to get those post IDs from?
The whole problem is that tapping a UI element doesn’t cause the post to show, I think we can accomplish this through selective unhiding in the post stream and don’t need to touch the query string at all.
Whatever solution is implemented should also activate on go-to-quote.
