Nike running trouble

Well, I created this enquiry, because I'm with some troubles with the Nike+ GPS (now Nike Running) app for iOS - I'm a iPod user -.

I got the app years ago and past month the app receives a new update, the 4.0, I'm a occasional runner that likes to run and share my run with friends, but now I'll explain what's might be wrong:

This is the Nike+ GPS 3.x version screenshot got on Google:

Look that the icons of start/end workout are bigger than the new's one that I got from a screenshot of my iPod:

Because I'm a big person with big hands and fingers, I've pressed the "end" workout many times when I just want to pause to take a rest, or drink water, this annoys me a lot.

Now as I'm a runner, I got a little problem with viewing the app, I use a convencional armband that locks my iPod on my arm, when I'm running on the day, and the sunlight beats on my iPod, I can't see NOTHING, because the plastic that covers my armband plus the sunlight make my view all-black.

I've looked into Nike+ site, and I got a solution:

The green color that Nike uses on the website is perfectly viewed from my armband+sunlight, plus on the night the green becomes much better to see instead of white. I don't know if anyone else had this trouble too, but I did a photomontage of what I would like to see on the main screen of the Nike Running app:

What i'm supposing to do is, make the numbers on a green color, make a little bit bigger buttons of "Resume Run" and "End" and another good thing that I guess it's good: a volume bar on the main screen too. Because imagine that you're running with a partner and the volume is too high, you might pause the run, exit the app, go to the Music app and down the volume, losing a few second or minutes...

I don't know if it's hard to do this changes, but please consider my opinion.
