Have different options for sorting topics

Please include different ways to sort topics besides just having them sorted by time posted by default. People should be able to sort topics by length (as in how many post there are) and popularity (how many times the topic has been added to favorites), in addition to the sorting system already implemented.

a very new site with not many functions right now but a very good suggestion.
there used to be a option on the old site so something like might come back.
