As you can see, the default at the moment (we may change this) is for the first post of a thread to be sticky (at the top) and every post after that will go from most recent, to oldest the further down the page. How do you like this system? EDIT switching back to classic mode for now, maybe let users choose the option.
I prefer new posts on top but don't mind setting the option on my end if it is not the default. Thanks for asking
