By far the biggest feature that is a MUST to return. Xbox Live was such a smooth experience for one reason; The Guide. All you had to do was press a button, choose your next destination, and you was there in seconds. Every necessity for Xbox Live was there with a press of a button, and for some reason the Sherlocks at Xbox decided to remove such a pivotal tool. A flaw of the Xbox One not having a Guide is shown on Messaging, with how a two-step process becoming a seven-step process. It baffles the mind how they could have come to the conclusion that the removal of a Guide would be more beneficial to the user, and have more fluidity. I have seen more than a few complain about the Interface, and how the younger audience have exceedingly struggled operating the Xbox One. Thats because with the Xbox 360, you had shortcuts. On the Xbox One, you don't. The sooner a Guide is implemented, the better. Because without it, the interface is truly terrible. What feature would you like to see added to the Xbox One? Comment below.
