FR: Order posts by most recent comment (and possibly other criteria)

[ognsya]

Usually I'll be most interested in seeing the most recent conversation about the URL I'm in.

Would be great if there were a way to sort the post tabs (from left to right) by the date of the latest comment (so the post with the most recent comment shows first, on the left).

Other sorting criteria could be useful too, such as:

• by post date
• by post activity (total comments maybe)
• by total likes
