How to sort a category list on 'Recent' or 'Popularity'

Question

When you click on a certain category, for example:

http://www.question2answer.org/qa/core

You will see that the questions are by default ordered on 'activity'.

Is there any way we can sort these question on 'Recent' or 'Popularity'?

This functionality is really missing within q2a...

Answer 1

Found one solution:

For 'Recent' use this URL:

How about sorting on most views or hotness?
