I'd like to see a designer speak up about using stuff like this more than one time. I find I'd hard to believe that you would sit down, after already playing around with this once, and say "this time I'm going to add a chevron to each cell, put the button on the left side, and go test it in the hallway". If your app is a table with a stock navigation system do you really ever need to build a second version of the same thing?
