[iOS] Peapod: better music controls for iPhone

I therefore give you Peapod, an app that lets you control the iPod on your iPhone. It features everything the built in app has, plus:

      

And some of the general browsing interface:

      

You can find the source on GitHub. You can also get a compiled watch app from here; as ever, getting a compiled phone app isn't something I can really help you with (but MacBuildServer generated this).

Usage: browse, pick music. You can toggle between volume controls and track controls by holding the select button briefly on the now playing screen.

Known issues: as usual, only one app at a time. Lists may briefly appear blank (though they shouldn't) if you scroll quickly. Selecting an item immediately after you stop scrolling may do nothing; if so, back out and repeat the selection. It should now work. It can only control the built-in music app from the on-device (or perhaps iTunes Match/iCloud) library. If you alter the playback state other than using the app it may get confused due to limitations on how apps in the background can observe music changes. Leaving and returning to the now playing interface and/or pausing/playing or changing track should probably fix this. If you have more than 1,170 items in a menu, the list will be truncated there due to the pervasive use of 16-bit signed integers in the Pebble UI framework.

Alpha or beta-ish quality, but hey. Let me know what you think!

As an aside, this project is also known as "why would anyone ever need more than 124 bytes?" Additionally, while writing it, I discovered the following:
