In mobile, it defaults to showing the Thead title, the user who posted the thread and the date it was posted. 

Is there ANYWAY you can substitute the User/Date of the initial post, to instead show the most User/Date of the most RECENT post??

I will pay whatever it costs for you guys to show me how to do this. I have a large community and this is very important to them. 

I know you'll want to say "Just use the extended theme" They also didn't like the extended Theme bc it was too busy and I was losing users.
