I was simply suggesting that you can use those actions in the app and randomly assigned what they should do. I like the double tapping for the article directly idea a lot.

I think the details toolbar is more useful where it is since I generally don't flag or upvote an item unless I read it. But that is a great idea (the swipe-for-options). You can include adding to Instapaper, and perhaps twitter/facebook/email sharing.

Also, a small bug: All the comments on the submissions say 0 points.
