Missing ability to sort by upzaps

[aChrisYouKnow]

Upzapping and downzapping is great, but seems kind of pointless if there isn't a sorting mechanism that uses the relative number of upzaps, downzaps, upvotes, and downvotes.

i.e. each of the below with the ability to select different timeframes (hour, day, week, etc.)

• 'Top' (upzaps minus downzaps)
• 'Best' (upzaps to downzaps ratio)
• 'Controversial' (lots of upzaps as well as downzaps)

I don't see anything related to sorting in the Features Checklist. Is this in the works? Already implemented and I'm just missing it?

Thanks!
