"1. An easy way to see what apps my friends are using and enjoying" Game Center does this for games, which is the use case he was specifically asking about. You dont even have to leave Game Center to read about and download your friend's game. "2. Ability to create 'playlists' and share them with friends" I've emailed lists of my favorite apps to friends. Not sure if I would maintain and vote on a playlist though. "3. Subscriptions to developers and push notifications to my device when they have released a new game" Smart developers already let you know about their new games by sending you messages in their games that you are currently playing. "4. Multiple categories for popular apps, such as 'Popular Today,' 'Popular This Month' and 'Popular All-Time' Seems reasonable, but it is just adding more lists to navigate in the already cluttered App Store. There are 5 main sections, and lots of sub lists: * Featured (New, What's Hot, Genius) * Categories (22 x [Top paid, top free, release date]) * Top 25 (Top Paid, Top Free, Top Grossing) * Search (N/A) * Updates (updates, purchased, not-on-this-device) "5. Saving games to a wishlist" Could be useful if it had a social component. Like if a grandma could get the app their kid wanted. Maybe? "6. A Sale category that shows which games are currently discounted from their normal cost" This would get gamed.
