In my opinion, the two most important features as a developer for the App Store:
1. Rolling deploys - right now releasing on iOS is scary and big bang, combined with the review process it keeps devs up at night worrying.
2. AB Testing on images and copy - you can only update this on each (scary) release, so you can't learn what works quickly.
