In the problem archive right now, we are able to sort the problems by the amount of people who solved it (and also filter by the subjects the problem requires), but that's it.
I was wondering whether we should have more options to sort by. For example, the feature to make a contest or a problem one of your "favourites" already exists, so what about being able to sort the problems in the archive by the number of people that made it one of their favourites? (Could also be applied to favourite contests.)
I'd be happy if more options were suggested in the comments, as I don't have many, but I am interested to hear some more.
