I only have 12 apps. I've only screwed with the bottom row of the first page and the dock. These are my apps, since there's only 12. Clash of Clans, Clash Royale, Boom Beach, Speedtest, BaconReader, YouTube, Google Inbox, ProTube, Microsoft Word, Purify, Netflix, and Amazon Instant Video.
I have around 60 applications on my iPhone, though. That's where my more "scattered" use is, along with social media. My iPad is for just those games, Reddit, Safari, YouTube, and Netflix. Much more specific, but pretty much THE things that you want a larger screen for.
