It would be nice if we could browse back further through past posts by order of last post... much like the "view today's active threads" or "view new posts" option, but expanded. Either it would show a certain number per page and allow full browsing back from the present, or we input a time period, say 3 days, and be shown all threads posted to, in order, over the last 3 days.

Quite often the new posts list will disappear, or only be 4 or 5 items long. I'd like to be able to see what I've missed, from a certain date or time, without having to click on all the different sections, and without subscribing to all threads.
