I would like to be able to scroll the lap times to look at them. I also wish more were shown at once (three instead of two previous laps at the least), similar to the Pebble stopwatch app.
This might interfere with swiping to change apps, which I only just realized is a thing, and I don't think is necessary since you can back out to the main screen. Being able to scroll in every app to add more functionality seems much more valuable.
