Just an idea for an option to be able to look for new addons which have had a sudden surge in popularity.
ie, when selected any recent addon which has had a large percentage increase in popularity would appear towards the top of find more. I guess it's a system that could be manipulated, but perhaps something like a minimum of 5000 downloads for an addon to appear towards the top to make it more difficult to just have all your friends download it a few times and give brand new addons a 5000% increase..
