The Xbox One seems to have fixed the UI problems with the 360.

You have your main screen.
-In the middle your most recent app.
-To the left you have your profile and friends list.
-to the right and down one you get your games library
-On the bottom are your four recent apps and next to it is the disc insert
-You also have three panels for recommendations.
That's pretty desgin and my only change would be to put the disc and collection tiles above the snap tile.

One bumper/swipe to the left brings up the pin aera where you can pin up to 20 apps/games that you enjoy.

One bumper/swipe to the right puts you at the store no longer being a ton of tabs.
